public override void BackwardTransform(
	Array2D<Complex<double>> input,
	Array2D<Complex<double>> output
)

Visual Basic

Public Overrides Sub BackwardTransform ( 
	input As Array2D(Of Complex(Of Double)),
	output As Array2D(Of Complex(Of Double))
)

C++/CLI

public:
virtual void BackwardTransform(
	Array2D<Complex<double>> input, 
	Array2D<Complex<double>> output
) override

abstract BackwardTransform : 
        input : Array2D<Complex<float>> * 
        output : Array2D<Complex<float>> -> unit 
override BackwardTransform : 
        input : Array2D<Complex<float>> * 
        output : Array2D<Complex<float>> -> unit

Parameters

input Array2D<Complex<Double>>: A complex number array containing the input signal.
output Array2D<Complex<Double>>: 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
