matplotlib does not support the `\begin{array}` construct. You can see
what is supported here:
http://matplotlib.org/users/mathtext.html
If you need something like that in Sphinx, there are a number of other
math plugins here:

The log of the simplest non-rendering formula:

{\Psi}^{L} \\

\end{array}
is as follows:

Subject: difficult LaTeX formula for rendering
Dear experts,
in our sphinx-based project documentation (www.diracprogram.org) we have a
complicated latex math formula, which is not rendered:
/usr/lib/pymodules/python2.7/matplotlib/sphinxext/mathmpl.py:56: Warning: Could
not render math expression $i \hbar \frac{\partial}{\partial t} \left(
\begin{array}{c}\Psi^L \\\Psi^S \end{array} \right) = c \left(
\begin{array}{c}(\vec{\sigma} \cdot \vec{\pi}) \Psi^S \\(\vec{\sigma} \cdot
\vec{\pi}) \Psi^L \end{array} \right)+ m_ec^2 \left( \begin{array}{c} \Psi^L
\\-\Psi^S \end{array} \right) + V \left( \begin{array}{c}\Psi^L \\\Psi^S
\end{array} \right)$
The index.rst file with the sole math formula is attached.
I have most recent Ubuntu 12.10 (x86_64) with default packages python-sphinx
1.1.2, python-matplotlib 1.1.1.
Any help, please ? I was trying to cut this formula down; the smallest LaTeX part not
rendered is "\begin{array}{c}\Psi^L \\ \Psi^S \end{array}".
Yours,
Miro
