<p dir="auto">Matrices and array environments would be useful to display with matplotlib.</p>

<p dir="auto">We'd also like support for our SymPy printing backends.

<p dir="auto">MPL currently has great math support for single line equations, but not for multiple line ones.  We ran into this problem when generating docs using sphinx.  The following snippet:</p>
<h3 dir="auto">/begin</h3>
<p dir="auto">.. math::</p>
<p dir="auto">E(t) = x + \delta(t)</p>
<p dir="auto">This type of experiment can be represented by two counting processes<br>
:math:<code class="notranslate">(E_a, E_b)</code> defined as</p>
<p dir="auto">.. math::</p>
<p dir="auto">\begin{aligned}<br>
E_a(t) &amp;=  a + \delta(t) <br>
E_b(t) &amp;=  b + \delta(t)<br>
\end{aligned}</p>
<h3 dir="auto">/end</h3>
<p dir="auto">has one single-line displayed equation, one inline and one multiline chunk.  The first two are rendered fine by MPL, but the latter fails.  It would be great to have MPL support this.</p>
<p dir="auto">While multiline equations are not too common in plots, they could be very useful in certain cases, if this feature was supported.</p>
