Thanks for your advice, but I'm not really sure how to handle that. I'm
really interested in using a binding through boost. I'm on a Mac and
I've been playing around with the Accelerate framework that comes along
with Mac OS. However, that's not nearly as nice as using Boost.Ublas
matrices. Do anyone know if I can bind to that framework or am I
dependent on some third library? What is the least painful way to get
hardware optimized matrix multiplication through that nice Boost.Ublas
interface?
Once again, thanks a lot for you answers,
