You can use pandoc to parse latex and convert it to mathml:
$ cat math.tex
\documentclass{amsart}
\begin{document}
\begin{align}
a &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
b &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
\\
c &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
d &= \begin{pmatrix}
1 & 2 & 3 \\
1 & 2 & 3 \\
1 & 2 & 3
\end{pmatrix},
\end{align}
\end{document}
$ pandoc -f latex -t html --mathml math.tex

Processing this in context (see attached files), gives a partially working solution. It doesn't look okay, but should be easily fixable.
Do note that this is almost same as compiling latex output to PDF because editing presentation mathml by hand is no fun.
