Tips on calling Matlab from Python

I've spent the past day or so working through the various complexities in
calling Matlab routines from Python (please do not reply with suggestions to
use Numpy/Scipy/etc. - our customer is using Matlab, and I needed to learn
how to access it through COM).

Matlab's COM API is actually pretty clean/simple, but there are a few
wrinkles, some undocumented "magic strings", and some odd surprises.  Also,
the Matlab COM API was designed for lesser languages that do not have
built-in support for complex data.  So I captured my usage notes, a simple
wrapper class, and some test code, to simplify this task.

You can find my notes at
