Fixing Matrix Formatting in Jekyll Blog | Generated by AI
The issue you’re facing is related to how Markdown (kramdown) processes the content before MathJax renders it. The double backslashes (\\) in your matrix are being interpreted by Markdown before MathJax gets to them, which breaks the matrix formatting.
Here are a few solutions to fix this:
Solution 1: Escape the backslashes
You can escape each backslash with another backslash:
$A - I = \begin{pmatrix} 1 & -3 & 0 \\\ 2 & 1 & 0 \\\ 0 & 0 & 2 \end{pmatrix} - \begin{pmatrix} 1 & 0 & 0 \\\ 0 & 1 & 0 \\\ 0 & 0 & 1 \end{pmatrix} = \begin{pmatrix} 0 & -3 & 0 \\\ 2 & 0 & 0 \\\ 0 & 0 & 1 \end{pmatrix}$
Solution 2: Use \\ inside math blocks
For display math (not inline), use $$ or \\\[ \\\]:
$$
A - I = \begin{pmatrix} 1 & -3 & 0 \\ 2 & 1 & 0 \\ 0 & 0 & 2 \end{pmatrix} - \begin{pmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{pmatrix} = \begin{pmatrix} 0 & -3 & 0 \\ 2 & 0 & 0 \\ 0 & 0 & 1 \end{pmatrix}
$$
Solution 3: Use HTML tags to prevent Markdown processing
Wrap your math in HTML div tags to prevent Markdown processing:
<div>
$$
A - I = \begin{pmatrix} 1 & -3 & 0 \\ 2 & 1 & 0 \\ 0 & 0 & 2 \end{pmatrix} - \begin{pmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{pmatrix} = \begin{pmatrix} 0 & -3 & 0 \\ 2 & 0 & 0 \\ 0 & 0 & 1 \end{pmatrix}
$$
</div>
Solution 4: Modify your kramdown configuration
Add this to your _config.yml to prevent kramdown from processing math blocks:
kramdown:
math_engine: mathjax
syntax_highlighter: rouge
Then you can use:
$$ A - I = \begin{pmatrix} 1 & -3 & 0 \\ 2 & 1 & 0 \\ 0 & 0 & 2 \end{pmatrix} - \begin{pmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & 0 & 1 \end{pmatrix} = \begin{pmatrix} 0 & -3 & 0 \\ 2 & 0 & 0 \\ 0 & 0 & 1 \end{pmatrix} $$
Try these solutions one by one to see which works best with your Jekyll setup. The most reliable solution is typically to use display math ($$ or \\\[ \\\]) instead of inline math ($) for matrices and other complex equations.
