I had forgotten about this case. I think when these were done it was thought that it would be better if the Numeric core did not require use of LAPACK/BLAS. We were thinking back then of a core with other packages, and the blas we use by default is probably the same speed so it didn't seem important. I would have no problem with a patch to change this. > -----Original Message----- > From: Jens Jorgen Mortensen [mailto:je...@fy...] > Sent: Thursday, February 20, 2003 9:00 AM > To: Paul F Dubois > Subject: Re: [Numpy-discussion] BLAS > > > On Torsdag den 20. februar 2003 17:49, Paul F Dubois wrote: > > > > When doing matrix-matrix multiplications with large > matrices, using > > > the BLAS library (Basic Linear Algebra Subprograms) can speed up > > > things a lot.
