well, that's not really fair. I've written extensions to Numeric (but 
the same would be true for numpy) that only work on 2-d double arrays -- 
that was easy. Generalizing to other types and shapes is a pain, but you 
don't even have that option with Matlab.

Yes, it is. But every tool, other than writing to the C API directly, 
takes care of that for you.

Yes, very cool. I haven't used it for anything real, but f2py looks very 
easy too, if you're working with Fortran.
