BackwardTransform(ArraySlice<Complex<Single>>, ArraySlice<Complex<Single>>)

Computes the discrete Fourier transform of a complex signal.
C#
public override void BackwardTransform(
	ArraySlice<Complex<float>> input,
	ArraySlice<Complex<float>> output
)

Parameters

input  ArraySlice<Complex<Single>>
A complex number array containing the input signal.
output  ArraySlice<Complex<Single>>
A complex number array to hold the transformed signal.

Exceptions

InvalidOperationException The FftDomain of the transform is not complex.

-or-

The input and output are the same, but the transform was not set up for in place calculation
