TMtx.IFFT2D Method (boolean)

Inverse two-dimensional Fast Fourier Transformation from complex to complex.

Pascal

function IFFT2D(NoScale: boolean = False): TMtx; overload;

Transformation is applied in-place. Source matrix must be complex. If source matrix is real, an exception will be raised. result matrix will be complex. Size of the calling matrix is not changed. NoScale parameter allows the scaling to be turned off.

Example

var a: TMtx; begin CreateIt(a); try a.SetIt (2,4,False, [1, 2, 3, 4, -5, 6,-7, 8] ); a.ExtendToComplex; a.IFFT2D; // result will be [(1.5, 0), (0, -0.5), (-3.5, 0), (0, 0.5), (1, 0), (-0.5, 0), (3, 0), (-0.5, 0) ] finally FreeIt(a); end; end;
