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

Hi,

I checked the source code. The symbol copy is defined in
blas1_overload.hpp, but not in blas1.hpp.

I recall that copy was not implemented because of the availability of
std::copy(), which should also work well.

Do you really want to use blas::copy ?
