Sorry for not beeing clear, I was talking about a generalized
hermitian-definite eigensystem. But with a matrix of type
gsl_matrix_complex_float instead of gsl_matrix_complex.

Yeah, I know. I already have an implementation with the corresponding
LAPACK routines. But I'd prefer to take GSL in this case.
Thanks anyway.
