What this means is that you'd be using python to drive your C++ code, 
rather than using C++ code to drive a python/mpl code. In addition to 
Boost::Python, there are some other options to consider:

pyrex, Cxx, SWIG.

The other option is to use your C++ code to drive Python. This can be 
done by embedding a python interpreter in your C++ app. See the 
odfficial pyhton docs, and lots of other stuff online.

You also might want to check out Elmer:

http://elmer.sourceforge.net/

I've never used it, but it looks pretty cool. It's a tool that provides 
the infrastructure for calling python from C/C++.

Honestly, though, I'd go with the first approach -- drive your C++ code 
from Python -- I think that in addition to making it easy to plot 
results, etc, you'll be able to write unit tests, etc in python, and 
even get a full scripting engine, which could turn out to be very useful..
