fft

Description:

public void fft (double timedata, F64Complex freqdata)

This performs the FFT on timedata and puts the result in freqdata.

timedata must have as many samples as specified with the len parameter while allocating the F64 instance with F64.

freqdata must be large enough to hold len/2 + 1 F64Complex frequency domain samples.

Parameters:

this

F64 instance for this call
timedata

Buffer of the samples in the time domain
freqdata

Target buffer for the samples in the frequency domain
