MathJax Configuration

Create or extend _includes/head_custom.html with:

{% assign math = page.math | default: layout.math | default: site.math %}

{% case math %}
  {% when "mathjax" %}
    {% include mathjax.html %}
{% endcase %}

Copy the following files to your website source repo:

For the source file _includes/mathjax.html from just-the-docs, we have updated the incorrectly set path from src="/just-the-docs/assets/js/mathjax-script-type.js" to the repositry root src="/assets/js/mathjax-script-type.js".

To make MathJax available on all your web pages, add to _config.yml:
```
math: mathjax
```
To restrict MathJax to pages that use it, add to the front matter either:
```
math: mathjax
```
or:
```
layout: mathjax
```
You can add a preamble of MathJax definitions of new commands and environments in _layouts/mathjax.html. It extends the default layout.

MathJax options

You can customise MathJax by adding further options in _includes/mathjax.html.

You can customise Just the Docs sites to support MathJax, as explained in the configuration suggestions. Pages then render $L A T E X$ code in kramdown math blocks using MathJax.

For example:

\begin{aligned} ϕ (x, y) = ϕ (\sum_{i = 1}^{n} x_{i} e_{i}, \sum_{j = 1}^{n} y_{j} e_{j}) = \sum_{i = 1}^{n} \sum_{j = 1}^{n} x_{i} y_{j} ϕ (e_{i}, e_{j}) = \\ (x_{1}, \dots, x_{n}) (\begin{array}{ccc} ϕ (e_{1}, e_{1}) & \dots & ϕ (e_{1}, e_{n}) \\ ⋮ & ⋱ & ⋮ \\ ϕ (e_{n}, e_{1}) & \dots & ϕ (e_{n}, e_{n}) \end{array}) (\begin{array}{c} y_{1} \\ ⋮ \\ y_{n} \end{array}) \end{aligned}
