Matrix IFFT2D(TMtx X, Boolean NoScale)
Computes the inverse discrete fourier transform of the source data.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TMtx | source TMtx |
| 2 | NoScale | Boolean |
Returns: Matrix
Remarks:
Internally calls Dew.Math.Matrix.IFFT2D
Examples
TMtx a;
TMtx b;
MtxVec.CreateIt(out a, out b);
try
{
a.SetIt (2,4,false,
[1, 2, 3, 4,
-5, 6,-7, 8] );
a.ExtendToComplex;
b.IFFT2D(a);
// 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
{
MtxVec.FreeIt(ref a, ref b);
}
