Forward two-dimentional Fast Fourier Transformation from real/complex to complex.

Pascal
function FFT2D: TMtx; overload;
Description

The transformation is applied in-place. The source matrix may be real or complex. The result will be always complex. The size of the calling matrix is not changed. (rows and cols will not chage).

Example
var a: Matrix; begin a.SetIt(2,4,False, [1, 2, 3, 4, -5, 6,-7, 8]); a.FFT2D; // result will be [(12,0), ( 0,4), (-28,0), (0,-4), ( 8,0), (-4,0), ( 24,0), (-4,0)] end;
