<h2>Matlab compatible commands</h2>

Matplotlib provides a number of matlab compatible plotting commands.
In addition to these, a large number of matlab compatible commands are
provided by Numeric's MLab, Numeric and FFT modules.
matplotlib.matlab imports these symbols, so when you do<p>

<pre>
from matplotlib.matlab import *
</pre>

you have access to all of Numeric and MLab, as well as some additional
matlab (non-plotting) compatible commands provided by matplotlib in
matplotlib.mlab.  Below is a (growing) list of matlab compatible
commands for use with Numeric and matplotlib.<p>

In addition, <a href=http://www.scipy.org/>scipy</a> provides many
more commands, but due to it's size, I haven't committed yet to making
it a requirement for matplotlib.<p>
