Detailed Description

template<typename _Tp>
class la::complex< _Tp >

Complex data type that can be used from the application.

This type is used for passing scalars in and out of LAPACK++. It is a copy of the std::complex<double> and it includes automatic conversion from and to std::complex<double>. Additionally it includes automatic conversion from and to the internal FORTRAN type COMPLEX, which is why this class is needed to pass complex values into Lapack++.

Again: If you get errors when passing a std::complex<double> into Lapack++, then you first need to convert your std::complex<double> into this LaComplex value.
