[Numpy-discussion] performance matrix multiplication vs. matlab
Fri Jan 8 08:18:28 CST 2010
I while back, someone talked about aigen2(http://eigen.tuxfamily.org/). In
their benchmark they give info that they are competitive again mkl and goto
on matrix matrix product. They are not better, but that could make a good
default implementation for numpy when their is no blas installed. I think
the license would allow to include it in numpy directly.
I don't have time to do it, and my numpy is linked with goto. So it would be
useless for me. But if someone want to make the default version better again
other tools, that could be a good approach.
