void FFT::fft_real_transform ( double *  data, size_t  stride, size_t  n  )

inline

Forward FFT for real data (packed output).

Computes the discrete Fourier transform of a real sequence and stores it in GSL halfcomplex packed format.

Parameters

data	Input/Output: real input sequence overwritten with packed spectrum.
stride	Input: element stride in data.
n	Input: number of samples.
