# Mathjax
To use [Mathjax] on a just-the-docs page:
- include `mathjax: true` in the YAML preamble
- enclose $$ \LaTeX $$ code in [kramdown math blocks]
The default Mathjax options in `_config.yml` are:
```yaml
compress_html:
blanklines: true # required for Mathjax
mathjax:
source: https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/latest.js?config=TeX-AMS_CHTML
config: 'MathJax.Hub.Config({ TeX: { equationNumbers: { autoNumber: "AMS" } } })'
```
Here is an example:
$$
\begin{align*}
& \phi(x,y) = \phi \left(\sum_{i=1}^n x_ie_i, \sum_{j=1}^n y_je_j \right)
= \sum_{i=1}^n \sum_{j=1}^n x_i y_j \phi(e_i, e_j) = \\
& (x_1, \ldots, x_n) \left( \begin{array}{ccc}
\phi(e_1, e_1) & \cdots & \phi(e_1, e_n) \\
\vdots & \ddots & \vdots \\
\phi(e_n, e_1) & \cdots & \phi(e_n, e_n)
\end{array} \right)
\left( \begin{array}{c}
y_1 \\
\vdots \\
y_n
\end{array} \right)
\end{align*}
$$
For further examples, see [this test page](test), adapted from a [test]
in [markdown-preview-plus].

$$x$$ math at the start of the document
Nested: $$M = \text{while e^2 $e^2$ do $c^2$ end}$$
**Numbered equations**
$$
\begin{equation}
\int_0^x \sin(x) dx
\label{eq:test}
\end{equation}
$$
$$\eqref{eq:test}$$
**Blockquotes**
> 1. A block quote
> 2. With a list inside
> 3. With $$math$$
**Math environment Syntax testing**
Inline Math should work with `$$` $$\frac{x+y}{y}$$
but not `\(` \(\frac{x+y}{y}\)
Use `$$` on separate lines:
$$
\int_{-\infty}^\infty e^{-x^2} = \sqrt{\pi}
$$
Use `$$` on the same line:
$$ \frac{-b \pm \sqrt{b^2-4ac}}{2a} $$
Use `$$` on separate lines:
$$
a+b
$$
Use `$$` on the same line: $$E=mc^2$$
----
**Some Tex Functions**
$$k \times k$$, $$n \times 2$$, $$2 \times n$$, $$\times$$
$$x \cdot y$$, $$\cdot$$
$$\sqrt{x^2+y^2+z^2}$$
$$\alpha \beta \gamma$$
$$
\begin{aligned}
x\ &= y\\
mc^2\ &= E
\end{aligned}
$$
----
**Escaped Math environments**
In the following examples no math environments should render:
a $5, a $10 and a \$100 Bill.
All McScrooge sees
\$$
and even more:
\$$
\\[x+y\]
\\(x+y\)
```
$x
```
```
\$
```
`\$`, `\[ \]`, `$x$`
----
**Testing `\newcommand`**
For all $$x$$ and $$y$$ in $$\mathbb{R}^k$$ it is true that
$$
\newcommand{sca}[1]{\langle #1 \rangle}
|\sca{x,y}|^2 \le \sca{x,x} \cdot \sca{y,y},
$$
<!-- newcommand not in environment-->
\newcommand{\scalong}[1]{(#1_1,\dots,#1_k)}
where $$\sca{\cdot,\cdot}$$ denotes the inner product $$\sca{\scalong{x}, \scalong{x}} = \sum_{i=1}^k x_i y_i$$.
----
**Testing several math fonts**
$$
p(\mathbf{m}) \sim \mathcal{N}(\mathbf{m}) e^{-\sum_{i} \beta_i m_i}
$$
$$
\langle \vec{m} \rangle =
\frac{1}{Z(\vec{\beta})}\vec{m}(\mu)
\sum_{\mu\in\mathcal{G}}
e^{-\vec{\beta}\cdot\vec{m}(\mu)}
$$
----
Notice below that the `$$`-separated display math doesn't have a blank line before and after (i.e. in an actual $$\LaTeX$$ document it wouldn't be placed in a separate paragraph):
The _characteristic polynomial_ $$\chi(\lambda)$$ of the
$$3 \times 3$$ matrix
$$
\left( \begin{array}{ccc}
a & b & c \\
d & e & f \\
g & h & i \end{array} \right)
$$
is given by the formula
$$
\chi(\lambda) = \left| \begin{array}{ccc}
\lambda - a & -b & -c \\
-d & \lambda - e & -f \\
-g & -h & \lambda - i \end{array} \right|.
$$
This is a long line: $$\chi(\lambda) = a e i-a e \lambda -a f h-a i \lambda +a \lambda ^2-b d i+b d \lambda +b f g+c d h-c e g+c g \lambda -e i \lambda +e \lambda ^2+f h \lambda +i \lambda ^2-\lambda ^3$$

**Does it work in different MD elements?**
# Math $$x^2$$ in heading 1
## Math $$x^2$$ in heading 2
### Math $$x^2$$ in heading 3
#### Math $$x^2$$ in heading 4
$$x_1, x_2, \dots, x_N$$ should not conflict with `_` _italics_?
$$(f*g*h)(x)$$ should not conflict with `*` *syn***tax**?
$$[a+b](c+d)$$ should not conflict link [syntax](#)?
_math $$x^2$$ in emphasis_
**math $$x^2$$ in bold**
[math $$x^2$$ in link](http://www.mathjax.org/)
`math $$x^2$$ in code`
~~math $$x^2$$ in strikethrough~~ (doesn't strike through the math)
