They have the same underlying representation, so there shouldn't be
any problem, cast away. FWIW, we already link gnuradio-core with GSL
(the GNU Scientific Library) which in turns links with CBLAS.

[Discuss-gnuradio] LAPACK/BLAS with GNURadio
Dear List,
I was trying to implement some LAPACK/BLAS(liblapack as included in
Ubuntu) wrappers for GNURadio since I haven't found anything to do
matrix/vector operations in GNURadio but I haven't found out how to do a
clever conversion from Fortran's (more precise the f2c) way of dealing
with complex numbers ( a C-struct ):
extern "C"
{
struct{
float real;
float imag;
} complex;
}
to the GNURadio way:
std::complex
and back.
My C++ knowledge on alignment etc. is too limited, up to now I just
copied them, since reinterpret_cast<> or static_cast<> only work for
certain architecture / alignment combinations. So if anyone has some
ideas please let me know.
Cheers,
Moritz
