Hi All, I have reached the point where I really need to get some sort of optimised/accelerated BLAS/LAPACK for windows 64 so have been trying a few different things out to see whether I can get anything usable, today i stumbled across this:
http://icl.cs.utk.edu/lapack-for-windows/index.html Has anyone used this before, I plan on seeing where it takes me in the morning, so I will report back if i get it working with numpy.
