Python vs. Matlab

Community matplotlib-users

All,

Lately folks in my office have started inquiring about the possibility
of porting some Matlab code to Python. They're mostly concerned about
cost and scriptability, but they're worried that the resulting Python
code would be very slow. The current Matlab version of the prime
porting target takes about 2 hours to run start to finish.

So I'm looking to either run some tests to prove that Python can keep up
or take someone else's results from similar tests and evangelize with
those.
I've googled "python vs. matlab" but most results seem to address
differences in the sort of code one has to write to achieve the same
ends, I'm interested in speed.

Anyone have any links or ammunition for the fight?

thanks,
Travis

Travis: There was a thread on this on Numpy-discussion a while back. Here's an excerpt:

Bottom line is that if you link the atlas libs, Numeric or numarray is comparable to Matlab for linear algebra (matrix multiply and eigenvector computation).
