\(\KaTeX\)

Just the Docs sites can be customised to support \(\KaTeX\), as explained in the configuration suggestions. Pages with math: katex in the front matter then render \(\LaTeX\) code in kramdown math blocks using \(\KaTeX\). For example:

\[\begin{aligned} & \phi(x,y) = \phi \left(\sum_{i=1}^n x_ie_i, \sum_{j=1}^n y_je_j \right) = \sum_{i=1}^n \sum_{j=1}^n x_i y_j \phi(e_i, e_j) = \\ & (x_1, \ldots, x_n) \left( \begin{array}{ccc} \phi(e_1, e_1) & \cdots & \phi(e_1, e_n) \\ \vdots & \ddots & \vdots \\ \phi(e_n, e_1) & \cdots & \phi(e_n, e_n) \end{array} \right) \left( \begin{array}{c} y_1 \\ \vdots \\ y_n \end{array} \right) \end{aligned}\]

To see the \(\LaTeX\) source of the formula, select the formula¹ and copy it to the clipboard.

Some tests illustrate the use of math in Markdown.
