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

Syntax
C#
Visual Basic
public TMtx FFT2D([In] TMtx Mtx);
Remarks

The transformation is applied on data in Mtx matrix and results are saved in the calling matrix. The source matrix may be real or complex. The source matrix is not changed. The calling matrix will be complex and will be of the same size as the source matrix. (rows and cols will not chage).

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