Latex Plugin For Pelican
|
|
========================
|
|
|
|
This plugin allows you to write mathematical equations in your articles using Latex.
|
|
It uses the MathJax Latex JavaScript library to render latex that is embedded in
|
|
between `$..$` for inline math and `$$..$$` for displayed math. It also allows for
|
|
writing equations in by using `\begin{equation}`...`\end{equation}`.
