Detailed Description

fft calculation.

System for calculating the fft (Fast Fourier Transform) of the input fvec. The actual fft code is scammed from the CARL software and is very similar to the fft implementation in Numerical Recipes. Returns an fvec of complex values (2*i, 2*i+1) = (Real, Imaginary).
