Function Documentation

template<class RealScalar> void serial_1D_FFT (  RealScalar  data[], unsigned long  nn, int  isign )

Simple templated function that implements a serial 1D complex-to-complex FFT. Replaces data[1..2*nn] by its discrete Fourier transform, if isign is input as 1; or replaces data[1..2*nn] by nn times its inverse discrete Fourier transform, if isign is input as -1. data is a complex array of length nn or, equivalently, a real array of length 2*nn. nn MUST be an integer power of 2 (this is not checked for!).
