I think everyone would be very happy to see numpy.dot modified to do this automatically. But adding a scipy.dot IMHO would be fixing things in the wrong place and just create extra confusion.
I am not sure I agree: numpy is often compiled without lapack support, as it is not necessary. On the other hand scipy is always compiled with lapack. Thus this makes more sens in scipy.
Well, numpy.dot already contains multiple fallback cases for when it is compiled with BLAS and not. So I'm +1 on just making this an improvement on numpy.dot. I don't think there's a time when you would not want to use this (provided the output order issue is fixed), and it doesn't make sense to not have old codes take advantage of the speed improvement.
Indeed, there is no reason not to make this available in NumPy.
Nicolas, can you prepare a patch for numpy ?
+1, I agree, this should be a fix in numpy, not scipy. Be Well Anthony
