Subject: Re: [ublas] ATLAS binding: error when multiplying a complex matrix by a real matrix

Thank you very much for your response.

Actually, ublas does support it, at least multiplication of complex
matrix by a real one (the other way gives a compilation error):

ublas::axpy_prod(C, R, O) -> works
ublas::axpy_prod(R, C, O) -> does not work

where C is complex, R is real, and O is complex

Cheers
Florent
