The support for TeX and LaTeX in MathJax consists of two parts: the tex2jax preprocessor, and the TeX input processor. The first of these looks for mathematics within your web page (indicated by math delimiters like

The tex2jax preprocessor can be configured to look for whatever markers you want to use for your math delimiters. See the tex2jax configuration options section for details on how to customize the action of tex2jax.

The TeX input processor handles conversion of your mathematical notation into MathJax’s internal format (which is essentially MathML), and so acts as a TeX to MathML converter. The TeX input processor has few configuration options, but it can also be customized through the use of extensions that define additional functionality.

Note that the TeX input processor implements**only** the math-mode macros of TeX and LaTeX, not the text-mode macros. MathJax expects that you will use standard HTML tags to handle formatting the text of your page; it only handles the mathematics. So, for example, MathJax does not implement

`$$...$$`

) and marks the mathematics for later processing by MathJax. The TeX input processor is what converts the TeX notation into MathJax’s internal format, where one of MathJax’s output processors then displays it in the web page.The tex2jax preprocessor can be configured to look for whatever markers you want to use for your math delimiters. See the tex2jax configuration options section for details on how to customize the action of tex2jax.

The TeX input processor handles conversion of your mathematical notation into MathJax’s internal format (which is essentially MathML), and so acts as a TeX to MathML converter. The TeX input processor has few configuration options, but it can also be customized through the use of extensions that define additional functionality.

Note that the TeX input processor implements

`\emph`

or `\begin{enumerate}...\end{enumerate}`

or other text-mode macros or environments. You must use HTML to handle such formatting tasks. If you need a LaTeX-to-HTML converter, you should consider other options.By default, the tex2jax preprocessor defines the LaTeX math delimiters, which are **not** define

MathJax.Hub.Config({ tex2jax: { inlineMath: [['$','$'], ['\\(','\\)']], processEscapes: true } });

Note that if you do this, you may want to also set*opening* math delimiter.)

See the

`\(...\)`

for in-line math, and `\[...\]`

for displayed equations. It also defines the TeX delimiters `$$...$$`

for displayed equations, but it does `$...$`

as in-line math delimiters. That is because dollar signs appear too often in non-mathematical settings, which could cause some text to be treated as mathematics unexpectedly. For example, with single-dollar delimiters, ”... the cost is $2.50 for the first one, and $2.00 for each additional one ...” would cause the phrase “2.50 for the first one, and” to be treated as mathematics since it falls between dollar signs. For this reason, if you want to use single-dollars for in-line math mode, you must enable that explicitly in your configuration:MathJax.Hub.Config({ tex2jax: { inlineMath: [['$','$'], ['\\(','\\)']], processEscapes: true } });

Note that if you do this, you may want to also set

`processEscapes`

to `true`

, as in the example above, so that you can use `\$`

to prevent a dollar sign from being treated as a math delimiter within the text of your web page. (Note that within TeX mathematics, `\$`

always has this meaning; `processEscapes`

only affects the treatment of the See the

`config/default.js`

file, or the tex2jax configuration options page, for additional configuration parameters that you can specify for the tex2jax preprocessor, which is the component of MathJax that identifies TeX notation within the page.Keep in mind that your mathematics is part of an HTML document, so you need to be aware of the special characters used by HTML as part of its markup. There cannot be HTML tags within the math delimiters (other than

... when $x<y$ we have ...

will cause a problem, because the browser will think

Usually, it is sufficient to simply put spaces around these symbols to cause the browser to avoid them, so

... when $x < y$ we have ...

should work. Alternatively, you can use the HTML entities

... when $x < y$ we have ...

Finally, there are

... when $x \lt y$ we have ...

Keep in mind that the browser interprets your text before MathJax does.

Another source of difficulty is when MathJax is used in content management systems that have their own document processing commands that are interpreted before the HTML page is created. For example, many blogs and wikis use formats like Markdown to allow you to create the content of you pages. In Markdown, the underscore is used to indicate italics, and this usage will conflict with MathJax’s use of the underscore to indicate a subscript. Since Markdown is applied to the page first, it will convert your subscripts markers into italics (inserting

Such systems need to be told not to modify the mathematics that appears between math delimiters. That usually involves modifying the content-management system itself, which is beyond the means of most page authors. If you are lucky, someone else will already have done this for you, and you can find a MathJax plugin for your system on the MathJax-In-Use page page.

If there is no plugin for your system, or if it doesn’t handle the subtleties of isolating the mathematics from the other markup that it supports, then you may have to “trick” it into leaving your mathematics untouched. Most content-management systems provide some means of indicating text that should not be modified (“verbatim” text), often for giving code snippets for computer languages. You may be use that to enclose your mathematics so that the system leaves it unchanged and MathJax can process it. For example, in Markdown, the back-tick (

... we have `\(x_1 = 132\)` and `\(x_2 = 370\)` and so ...

may be able to protect the underscores from being processed by Markdown.

Some content-management systems use the backslash (

\\begin{array}{cc} a & b \\\\ c & c \\end{array}

to get an array with the four entries*a*, *b*, *c*, and *d*. Note in particular that if you want *both* backslashes, giving

Finally, if you have enabled single dollar-signs as math delimiters, and you want to include a literal dollar sign in your web page (one that doesn’t represent a math delimiter), you will need to prevent MathJax from using it as a math delimiter. If you also enable the

`<br>`

) as TeX-formatted math does not include HTML tags. Also, since the mathematics is initially given as text on the page, you need to be careful that your mathematics doesn’t look like HTML tags to the browser (which parses the page before MathJax gets to see it). In particular, that means that you have to be careful about things like less-than and greater-than signs (`<`

and `>`

), and ampersands (`&`

), which have special meaning to the browsers. For example,... when $x<y$ we have ...

will cause a problem, because the browser will think

`<y`

is the beginning of a tag named `y`

(even though there is no such tag in HTML). When this happens, the browser will think the tag continues up to the next `>`

in the document (typically the end of the next actual tag in the HTML file), and you may notice that you are missing part of the text of the document. In the example above, the “```
we
have ...
```

” will not be displayed because the browser thinks it is part of the tag starting at `<y`

. This is one indication you can use to spot this problem; it is a common error and should be avoided.Usually, it is sufficient to simply put spaces around these symbols to cause the browser to avoid them, so

... when $x < y$ we have ...

should work. Alternatively, you can use the HTML entities

`<`

, `>`

and `&`

to encode these characters so that the browser will not interpret them, but MathJax will. E.g.,... when $x < y$ we have ...

Finally, there are

`\lt`

and `\gt`

macros defined to make it easier to enter `<`

and `>`

using TeX-like syntax:... when $x \lt y$ we have ...

Keep in mind that the browser interprets your text before MathJax does.

Another source of difficulty is when MathJax is used in content management systems that have their own document processing commands that are interpreted before the HTML page is created. For example, many blogs and wikis use formats like Markdown to allow you to create the content of you pages. In Markdown, the underscore is used to indicate italics, and this usage will conflict with MathJax’s use of the underscore to indicate a subscript. Since Markdown is applied to the page first, it will convert your subscripts markers into italics (inserting

`<i>`

tags into your mathematics, which will cause MathJax to ignore the math).Such systems need to be told not to modify the mathematics that appears between math delimiters. That usually involves modifying the content-management system itself, which is beyond the means of most page authors. If you are lucky, someone else will already have done this for you, and you can find a MathJax plugin for your system on the MathJax-In-Use page page.

may be able to protect the underscores from being processed by Markdown.

Some content-management systems use the backslash (

`\`

) as a special character for “escaping” other characters, but TeX uses this character to indicate a macro name. In such systems, you may have to double the backslashes in order to obtain a single backslash in your HTML page. For example, you may have to do\\begin{array}{cc} a & b \\\\ c & c \\end{array}

to get an array with the four entries

`\\`

you will have to double `\\\\`

.Finally, if you have enabled single dollar-signs as math delimiters, and you want to include a literal dollar sign in your web page (one that doesn’t represent a math delimiter), you will need to prevent MathJax from using it as a math delimiter. If you also enable the

`processEscapes`

configuration parameter, then you can use `\$`

in the text of your page to get a dollar sign (without the backslash) in the end. Alternatively, you use something like `<span>$</span>`

to isolate the dollar sign so that MathJax will not use it as a delimiter.You can use the

\( \def\RR{\bf R} \def\bold#1{\bf #1} \)

would define

You can include macro definitions in the Macros section of the TeX blocks of your configuration, but they must be represented as JavaScript objects. For example, the two macros above can be pre-defined in the configuration by

MathJax.Hub.Config({ TeX: { Macros: { RR: "{\\bf R}", bold: ["{\\bf #1}",1] } } });

Here you give the macro as a name:value pair, where the name is the name of the control sequence (without the backslash) that you are defining, and value is either the replacement string for the macro (when there are no arguments) or an array consisting of the replacement string followed by the number of arguments for the macro.

Note that the replacement string is given as a JavaScript string literal, and the backslash has special meaning in JavaScript strings. So to get an actual backslash in the string you must double it, as in the examples above.

If you have many such definitions that you want to use on more than one page, you could put them into a configuration file that you can load along with the main configuration file. For example, you could create a file in

MathJax.Hub.Config({ TeX: { Macros: { RR: "{\\bf R}", bold: ["{\\bf #1}",1] } } }); MathJax.Ajax.loadComplete("[MathJax]/config/local/local.js");

and then load it along with your main configuration file on the script that loads

<script src="/MathJax/MathJax.js?config=TeX-AMS_HTML,local/local.js"></script>

If you are using the CDN, you can make a local configuration file on your own server, and load MathJax itself from the CDN and your configuration file from your server. See Using a Local Configuration File with the CDN for details.

`\def`

, `\newcommand`

, `\renewcommand`

, `\newenvironment`

, `\renewenvironment`

, and `\let`

commands to create your own macros and environments. Unlike actual TeX, however, in order for MathJax to process these, they must be enclosed in math delimiters (since MathJax only processes macros in math-mode). For example\( \def\RR{\bf R} \def\bold#1{\bf #1} \)

would define

`\RR`

to produce a bold-faced “R”, and `\bold{...}`

to put its argument into bold face. Both definitions would be available throughout the rest of the page.You can include macro definitions in the Macros section of the TeX blocks of your configuration, but they must be represented as JavaScript objects. For example, the two macros above can be pre-defined in the configuration by

`MathJax/config/local`

called `local.js`

that contains your macro definitions:MathJax.Hub.Config({ TeX: { Macros: { RR: "{\\bf R}", bold: ["{\\bf #1}",1] } } }); MathJax.Ajax.loadComplete("[MathJax]/config/local/local.js");

and then load it along with your main configuration file on the script that loads

New in MathJax v2.0 is the ability to have equations be numbered automatically. This functionality is turned off by default, so that pages don’t change when you update from v1.1 to v2.0, but it is easy to configure MathJax to produce automatic equation numbers by adding:

<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { equationNumbers: { autoNumber: "AMS" } } }); </script>

to your page just before the

Equations can be numbered in two ways: either number the AMSmath environments as LaTeX would, or number all displayed equations (the example above uses AMS-style numbering). Set

Note that the AMS environments come in two forms: starred and unstarred. The unstarred versions produce equation numbers (when

\begin{equation} E = mc^2 \end{equation}

will be numbered, while

\begin{equation*} e^{\pi i} + 1 = 0 \end{equation*}

won’t be numbered (when

You can use

In equation \eqref{eq:sample}, we find the value of an interesting integral: \begin{equation} \int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15} \label{eq:sample} \end{equation}

includes a labeled equation and a reference to that equation. Note that references can come before the corresponding formula as well as after them. See the equation numbering links in the MathJax examples page for more examples.

You can configure the way that numbers are displayed and how the references to them are made using parameters in the

<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { equationNumbers: { autoNumber: "AMS" } } }); </script>

to your page just before the

`<script>`

tag that loads `MathJax.js`

itself.Equations can be numbered in two ways: either number the AMSmath environments as LaTeX would, or number all displayed equations (the example above uses AMS-style numbering). Set

`autoNumber`

to `"all"`

if you want every displayed equation to be numbered. You can use `\notag`

or `\nonumber`

to prevent individual equations from being numbered, and `\tag{}`

can be used to override the usual equation number with your own symbol instead.Note that the AMS environments come in two forms: starred and unstarred. The unstarred versions produce equation numbers (when

`autoNumber`

is set to `"AMS"`

) and the starred ones don’t. For example\begin{equation} E = mc^2 \end{equation}

will be numbered, while

\begin{equation*} e^{\pi i} + 1 = 0 \end{equation*}

won’t be numbered (when

`autoNumber`

is `"AMS"`

).You can use

`\label`

to give an equation an identifier that you can use to refer to it later, and then use `\ref`

or `\eqref`

within your document to insert the actual equation number at that location, as a reference. For example,In equation \eqref{eq:sample}, we find the value of an interesting integral: \begin{equation} \int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15} \label{eq:sample} \end{equation}

includes a labeled equation and a reference to that equation. Note that references can come before the corresponding formula as well as after them. See the equation numbering links in the MathJax examples page for more examples.

You can configure the way that numbers are displayed and how the references to them are made using parameters in the

`equationNumbers`

block of your `TeX`

configuration. See the TeX configuration options page for more details.While MathJax includes nearly all of the Plain TeX math macros, and many of the LaTeX macros and environments, not everything is implemented in the core TeX input processor. Some less-used commands are defined in extensions to the TeX processor. MathJax will load some extensions automatically when you first use the commands they implement (for example, the

To enable any of the TeX extensions, simply add the appropriate string (e.g.,

<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { extensions: ["autobold.js"] }}); </script> <script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"> </script>

will load the autobold TeX extension in addition to those already included in the

You can also load these extensions from within a math expresion using the non-standard

\(\require{color}\)

would load the color extension into the page. This way you you can load extensions into pages that didn’t load them in their configurations (and prevents you from having to load all the extensions into all pages even if they aren’t used).

It is also possible to create a macro that will autoload an extension when it is first used (under the assumption that the extension will redefine it to perform its true function). For example

<script type="text/x-mathjax-config"> MathJax.Hub.Register.StartupHook("TeX Jax Ready",function () { MathJax.Hub.Insert(MathJax.InputJax.TeX.Definitions.macros,{ cancel: ["Extension","cancel"], bcancel: ["Extension","cancel"], xcancel: ["Extension","cancel"], cancelto: ["Extension","cancel"] }); }); </script>

would declare the*not* used. The sample autoloading macros example page shows this in action. The autoload-all extension below defines such macros for *all* the extensions so that if you include it, MathJax will have access to all the macros it knows about.

The main extensions are described below.

`\def`

and `\newcommand`

macros are implemented in the `newcommand.js`

extension, but MathJax loads this extension itself when you use those macros). Not all extensions are set up to load automatically, however, so you may need to request some extensions explicitly yourself.To enable any of the TeX extensions, simply add the appropriate string (e.g.,

`"AMSmath.js"`

) to the extensions array in the `TeX`

block of your configuration. If you use one of the combined configuration files, like `TeX-AMS_HTML`

, this will already include several of the extensions automatically, but you can include others using a mathjax configuration script prior to loading MathJax. For example<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { extensions: ["autobold.js"] }}); </script> <script type="text/javascript" src="http://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML"> </script>

will load the autobold TeX extension in addition to those already included in the

`TeX-AMS_HTML`

configuration file.You can also load these extensions from within a math expresion using the non-standard

`\require{extension}`

macro. For example\(\require{color}\)

would load the color extension into the page. This way you you can load extensions into pages that didn’t load them in their configurations (and prevents you from having to load all the extensions into all pages even if they aren’t used).

It is also possible to create a macro that will autoload an extension when it is first used (under the assumption that the extension will redefine it to perform its true function). For example

would declare the

`\cancel`

, `\bcancel`

, `\xcancel`

, and `\cancelto`

macros to load the cancel extension (where they are actually defined). Whichever is used first will cause the extension to be loaded, redefining all four to their proper values. Note that this may be better than loading the extension explicitly, since it avoids loading the extra file on pages where these macros are The main extensions are described below.

The action extension gives you access to the MathML

`<maction>`

element. It defines three new non-standard macros:`\mathtip{math}{tip}`

- Use
`tip`

(in math mode) as tooltip for`math`

.

`\texttip{math}{tip}`

- Use
`tip`

(in text mode) as tooltip for`math`

.

`\toggle{math1}{math2}...\endtoggle`

- Show
`math1`

, and when clicked, show`math2`

, and so on. When the last one is clicked, go back to math1.

The bbox extension defines a new macro for adding background colors, borders, and padding to your math expressions.

`\bbox[options]{math}`

- puts a bounding box around
`math`

using the provided`options`

. The options can be one of the following:- A color name used for the background color.
- A dimension (e.g.,
`2px`

) to be used as a padding around the mathematics (on all sides). - Style attributes to be applied to the mathematics (e.g.,
`border:1px solid red`

). - A combination of these separated by commas.

Here are some examples:

\bbox[red]{x+y} % a red box behind x+y \bbox[2pt]{x+1} % an invisible box around x+y with 2pt of extra space \bbox[red,2pt]{x+1} % a red box around x+y with 2pt of extra space \bbox[5px,border:2px solid red] % a 2px red border around the math 5px away

The extpfeil extension adds more macros for producing extensible arrows, including

`\xtwoheadrightarrow`

, `\xtwoheadleftarrow`

, `\xmapsto`

, `\xlongequal`

, `\xtofrom`

, and a non-standard `\Newextarrow`

for creating your own extensible arrows. The latter has the form`\Newextarrow{\cs}{lspace,rspace}{unicode-char}`

- where
`\cs`

is the new control sequence name to be defined,`lspace`

and`rspace`

are integers representing the amount of space (in suitably small units) to use at the left and right of text that is placed above or below the arrow, and`unicode-char`

is a number representing a unicode character position in either decimal or hexadecimal notation.

For example

\Newextarrow{\xrightharpoonup}{5,10}{0x21C0}

defines an extensible right harpoon with barb up. Note that MathJax knows how to stretch only a limited number of characters, so you may not actually get a stretchy character this way.

The HTML extension gives you access to some HTML features like styles, classes, element ID’s and clickable links. It defines the following non-standard macros:

`\href{url}{math}`

- Makes
`math`

be a link to the page given by`url`

.

`\class{name}{math}`

- Attaches the CSS class
`name`

to the output associated with`math`

when it is included in the HTML page. This allows your CSS to style the element.

`\cssId{id}{math}`

- Attaches an id attribute with value
`id`

to the output associated with`math`

when it is included in the HTML page. This allows your CSS to style the element, or your javascript to locate it on the page.

`\style{css}{math}`

- Adds the give
`css`

declarations to the element associated with`math`

.

For example:

x \href{why-equal.html}{=} y^2 + 1 (x+1)^2 = \class{hidden}{(x+1)(x+1)} (x+1)^2 = \cssId{step1}{\style{visibility:hidden}{(x+1)(x+1)}}

This extension is**not** included in any of the combined configurations, but it will be loaded automatically when any of these macros is used, so you do not need to include it explicitly in your configuration.

The noErrors extension prevents TeX error messages from being displayed and shows the original TeX code instead. You can configure whether the dollar signs are shown or not for in-line math, and whether to put all the TeX on one line or use multiple lines (if the original text contained line breaks).

This extension is loaded by all the combined configuration files that include the TeX input processor. To enable the noErrors extension in your own configuration, or to modify its parameters, add something like the following to your

TeX: { extensions: ["noErrors.js"], noErrors: { inlineDelimiters: ["",""], // or ["$","$"] or ["\\(","\\)"] multiLine: true, // false for TeX on all one line style: { "font-size": "90%", "text-align": "left", "color": "black", "padding": "1px 3px", "border": "1px solid" // add any additional CSS styles that you want // (be sure there is no extra comma at the end of the last item) } } }

Display-style math is always shown in multi-line format, and without delimiters, as it will already be set off in its own centered paragraph, like standard display mathematics.

The default settings place the invalid TeX in a multi-line box with a black border. If you want it to look as though the TeX is just part of the paragraph, use

TeX: { noErrors: { inlineDelimiters: ["$","$"], // or ["",""] or ["\\(","\\)"] multiLine: false, style: { "font-size": "normal", "border": "" } } }

You may also wish to set the font family or other CSS values here.

If you are using a combined configuration file that loads the TeX input processor, it will also load the noErrors extension automatically. If you want to disable the noErrors extension so that you receive the normal TeX error messages, use the following configuration:

TeX: { noErrors: { disabled: true } }

Any math that includes errors will be replaced by an error message indicating what went wrong.

This extension is loaded by all the combined configuration files that include the TeX input processor. To enable the noErrors extension in your own configuration, or to modify its parameters, add something like the following to your

`MathJax.Hub.Config()`

call:TeX: { extensions: ["noErrors.js"], noErrors: { inlineDelimiters: ["",""], // or ["$","$"] or ["\\(","\\)"] multiLine: true, // false for TeX on all one line style: { "font-size": "90%", "text-align": "left", "color": "black", "padding": "1px 3px", "border": "1px solid" // add any additional CSS styles that you want // (be sure there is no extra comma at the end of the last item) } } }

The noUndefined extension causes undefined control sequences to be shown as their macro names rather than generating error messages. So

This extension is loaded by all the combined configuration files that include the TeX input processor. To enable the noUndefined extension in your own configuration, or to modify its parameters, add something like the following to your

If you are using a combined configuration file that loads the TeX input processor, it will also load the noUndefined extension automatically. If you want to disable the noUndefined extension so that you receive the normal TeX error messages for undefined macros, use the following configuration:

TeX: { noUndefined: { disabled: true } }

Any math that includes an undefined control sequence name will be replaced by an error message indicating what name was undefined.

`$X_{\xxx}$`

would display as an “X” with a subscript consisting of the text `\xxx`

in red.This extension is loaded by all the combined configuration files that include the TeX input processor. To enable the noUndefined extension in your own configuration, or to modify its parameters, add something like the following to your

`MathJax.Hub.Config()`

call:TeX: { extensions: ["noUndefined.js"], noUndefined: { attributes: { mathcolor: "red", mathbackground: "#FFEEEE", mathsize: "90%" } } }

The

`attributes`

setting specifies attributes to apply to the `mtext`

element that encodes the name of the undefined macro. The default values set `mathcolor`

to `"red"`

, but do not set any other attributes. This example sets the background to a light pink, and reduces the font size slightly.If you are using a combined configuration file that loads the TeX input processor, it will also load the noUndefined extension automatically. If you want to disable the noUndefined extension so that you receive the normal TeX error messages for undefined macros, use the following configuration:

TeX: { noUndefined: { disabled: true } }

Any math that includes an undefined control sequence name will be replaced by an error message indicating what name was undefined.

The unicode extension implements a

Examples:

\unicode{65} % the character 'A' \unicode{x41} % the character 'A' \unicode[.55,0.05]{x22D6} % less-than with dot, with height .55em and depth 0.05em \unicode[.55,0.05][Geramond]{x22D6} % same taken from Geramond font \unicode[Garamond]{x22D6} % same, but with default height, depth of .8em,.2em

Once a size and font are provided for a given unicode point, they need not be specified again in subsequent

The result of

Note that a font list can be given in the

The unicode extension is loaded automatically when you first use the

TeX: { unicode: { fonts: "STIXGeneral, 'Arial Unicode MS'" } }

`\unicode{}`

extension to TeX that allows arbitrary unicode code points to be entered in your mathematics. You can specify the height and depth of the character (the width is determined by the browser), and the default font from which to take the character.Examples:

\unicode{65} % the character 'A' \unicode{x41} % the character 'A' \unicode[.55,0.05]{x22D6} % less-than with dot, with height .55em and depth 0.05em \unicode[.55,0.05][Geramond]{x22D6} % same taken from Geramond font \unicode[Garamond]{x22D6} % same, but with default height, depth of .8em,.2em

Once a size and font are provided for a given unicode point, they need not be specified again in subsequent

`\unicode{}`

calls for that character.The result of

`\unicode{...}`

will have TeX class ORD (i.e., it will act like a variable). Use `\mathbin{...}`

, `\mathrel{...}`

, etc., to specify a different class.Note that a font list can be given in the

`\unicode{}`

macro, but Internet Explorer has a buggy implementation of the `font-family`

CSS attribute where it only looks in the first font in the list that is actually installed on the system, and if the required glyph is not in that font, it does not look at later fonts, but goes directly to the default font as set in the Internet-Options/Font panel. For this reason, the default font list for the `\unicode{}`

macro is `STIXGeneral, 'Arial Unicode MS'`

, so if the user has STIX fonts, the symbol will be taken from that (almost all the symbols are in STIXGeneral), otherwise MathJax tries Arial Unicode MS.The unicode extension is loaded automatically when you first use the

`\unicode{}`

macro, so you do not need to add it to the extensions array. You can configure the extension as follows:TeX: { unicode: { fonts: "STIXGeneral, 'Arial Unicode MS'" } }

The autoload-all extension predefines all the macros from the extensions above so that they autoload the extensions when first used. A number of macros already do this, e.g.,

To use this extension in your own configurations, add it to the extensions array in the TeX block.

TeX: { extensions: ["autoload-all.js"] }

This extension is**not** included in any of the combined configurations, and will not be loaded automatically, so you must include it explicitly in your configuration if you wish to use these commands.

Note that autoload-all redefines

If you wish to retain the original definition of

<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { extensions: ["autoload-all.js"] } }); MathJax.Hub.Register.StartupHook("TeX autoload-all Ready", function () { var MACROS = MathJax.InputJax.TeX.Definitions.macros; MACROS.color = "Color"; delete MACROS.colorbox; delete MACROS.fcolorbox; }); </script>

`\unicode`

, but this extension defines the others to do the same. That way MathJax will have access to all the macros that it knows about.To use this extension in your own configurations, add it to the extensions array in the TeX block.

TeX: { extensions: ["autoload-all.js"] }

This extension is

Note that autoload-all redefines

`\color`

to be the one from the color extension (the LaTeX-compatible one rather than the non-standard MathJax version). This is because `\colorbox`

and `\fcolorbox`

autoload the color extension, which will cause `\color`

to be redefined, and so for consistency, `\color`

is redefined immediately.If you wish to retain the original definition of

`\color`

, then use the following<script type="text/x-mathjax-config"> MathJax.Hub.Config({ TeX: { extensions: ["autoload-all.js"] } }); MathJax.Hub.Register.StartupHook("TeX autoload-all Ready", function () { var MACROS = MathJax.InputJax.TeX.Definitions.macros; MACROS.color = "Color"; delete MACROS.colorbox; delete MACROS.fcolorbox; }); </script>

This is a long list of the TeX macros supported by MathJax. If the macro is defined in an extension, the name of the extension follows the macro name. If the extension is in brackets, the extension will be loaded automatically when the macro or environment is first used.
