RE: [Numpy-discussion] BLAS
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.

When doing matrix-matrix multiplications with large matrices, using the BLAS library (Basic Linear Algebra Subprograms) can speed up things a lot. I don't think Numeric takes advantage of this (is this correct?).
No. You can configure it at installation to use the BLAS of choice.
I know that the stuff in LinearAlgebra can be configured to use a BLAS of choice, but what about the Numeric.dot function?
Can I configure Numeric so that this:
a = Numeric.dot(b, c)
will use BLAS?
