Hello,

Travis asked me to benchmark numpy versus matlab in some basic linear algebra operations. Here are the resuts for matrices/vectors of dimensions 5, 50 and 500:

Hi Paulo,

Will you run these again with the latest SVN version of numpy. I couldn't figure out why a copy was being made on transpose (because it shouldn't have been). Then, I dug deep into the PyArray_FromAny code and found bad logic in when a copy was needed that was causing an inappropriate copy.

I fixed that and now wonder how things will change. Because presumably, the dotblas function should handle the situation now...
