[Numpy-discussion] performance matrix multiplication vs. matlab
Sun Jun 7 13:47:13 CDT 2009
when i had problems building atlas in the past (i.e. numpy.test()
failed) it was a problem with my lapack build, not atlas. The netlib
website gives instructions for building the lapack test suite. I
suggest you do that and run the tests on lapack and make sure
everything is kosher.
