Re: [ublas] Missing "copy" in BLAS bindings?

From: Francisco Javier González Varel (fgonzalez_at_[hidden])
Date: 2007-03-27 04:32:41

My code includes the lines

using namespace boost::numeric::bindings::blas;
//using namespace boost::numeric::bindings::atlas;

(sorry, I didn't include them in the code in the other e-mail)

In fact, the program uses the atlas function "copy" when I use the  
atlas bindings, but this doesn't happen with the blas bindings.

Thanks!
