Yes, I was looking at that too, but would have to order a copy.  Might be
worth it since some of the other guys doing simulation and analysis are
using it.  If nothing else, having Matlab might minimize the fear factor
of interfacing with me and my "strange Linux world".

I just installed Octave, and it does look like it should work.  However,
it is another language to learn.  I don't suppose I could talk you out of
a sample Matlab script?

The other thing I was just checking out is the new Signal Processing
Toolbox (Signaltools 0.5.3) in Python.  Looks like I'll have to download
that to see what it really contains.  The biggest advantage with this is
that I already have some experience writing simple Python programs, and
can probably get my data in and out without much trouble.
