TVec.IFFT Method (boolean)

The inverse backward FFT from complex to complex.

Pascal
function IFFT(NoScale: boolean = False): TVec; overload;

Calculates the inverse (backward) Fast Fourier Transformation (FFT) from complex to complex for all calling vector elements in-place. If the NoScale parameter is true, then no scaling is performed for the calling vector. The results can be erroneous if overflow or underflow occurs.

var a,b: TVec; begin CreateIt(a,b); try a.SetIt(True,[1,2,3,4]); b.IFFT(a,True); finally FreeIt(a,b); end; end;
