I have no interest in supporting an interface to MATLAB, or any other
proprietary software for that matter.  I'd be much more interested in
working with Octave, or better yet, working up an excellent
interface to scipy.   Just because EE's are trained in MATLAB, doesn't
mean that it's even a reasonable tool to use.   Do you know of any
other language the allows only a single externally visible function
PER FILE???  Come on folks, stop drinking the kool-aid.

matplotlib supports pretty much all the high-level plotting features
found in MATLAB, and does it in Python, a language that provides a lot
more leverage than MATLAB.  scipy's got all the linear algebra, and
and ever expanding set of functions / toolboxes.

No offense, but I think that EE professors are part of the problem.
Many of them have little or no real world programming experience.
You can tell.  They think that MATLAB is a "reasonable" language.
