Re: [Matplotlib-users] difficult LaTeX formula for rendering

Hi again,

if you did not receive the attachement of my previous email, the files are here:

https://docs.google.com/folder/d/0B8qBHKNhZAipZ2pnS0ViTUZBdXM/edit?usp=sharing

The log of the simplest non-rendering formula:

.. math::
 \begin{array}{c}
 {\Psi}^{L} \\
 {\Psi}^{S} 
 \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
