Typedef Documentation

typedef complex<float_type> SPUC::CPLX

General Purpose C++ complex FFT Transform.

This is a general-purpose C++ complex FFT transform class. it is defined as a template over a complex type. For instance, if using gnu gcc, the complex type is complex<float_type> And you declare the cfft class as cfft<complex<float_type>>

The underlying CPLX type requires: CPLX() operator = , CPLX(CPLX const&) CPLX(float_type,float_type) [used on cos/sin] CPLX operator*( CPLX , float_type ) CPLX conj(CPLX const &); [conjugate] ComPlex::operator @ (CPLX , CPLX ) [ where @ =* + - ]
