I agree.
My point was a bit of a side issue: given a user's computer, I have no
garantee that numpy will be compiled with an optimized blas. In fact, I
have often seen on computing clusters where people tend to compile stuff
manually numpy using the embedded lapack_lite. On the other hand, scipy
is necessarily compiled using a blas. This is why, as a developer, I
always write code that uses scipy.linalg rather than numpy.linalg.
However, for 'dot', I have no way of ensuring that the blas used to
compile scipy is used.
Cheers,
Gaël
