efficient than manually creating an Fft object for a single use, as the Fft object is deterministically destroyed before these functions return.
fft
fn
Complex!F[] fft(F = double, R)(R range)Convenience functions that create an Fft object, run the FFT or inverse FFT and return the result. Useful for one-off FFTs.
Note
In addition to convenience, these functions are slightly more
fn
void fft(Ret, R)(R range, Ret buf)ditto
