float_complex *  signal 
) [static, protected]

Prime number size FFT where the signal has a sampling not equal to 1, i.e. every Nth value should be used.

Parameters:
dir 1 for forward, -1 for backwards
sz Length of signal
step is the step between the samples of the signal
signal Is the signal itself. The output will be written to signal.
