Computes the forward 1D FFT of each row in arrayinout and returns the complex conjugate symmetric results in-place in a packed format.

Namespace:  CenterSpace.NMath.Core
Assembly:  NMath (in NMath.dll) Version: 5.1.0.0

Syntax

C#
public void FFTInPlaceArray(
	double[,] arrayinout
)
Visual Basic (Declaration)
Public Sub FFTInPlaceArray ( _
	arrayinout As Double(,) _
)
Visual C++
public:
void FFTInPlaceArray(
	array<double,2>^ arrayinout
)

Parameters

arrayinout
Type: array< System..::.Double ,2>[,](,)[,]
Array of row-wise of input signals.

Remarks

If signals are all the same length, this is computationally more efficient than computing each FFT one at a time using a signal vector. Get a DoubleSymmetricSignalReader instance by calling the GetSignalReader() method to extract individual signal FFT's out of the complex conjugate symmetric packed resultant array. Replaces deprecated FFTInPlace(double[,] arrayinout).

Exceptions

ExceptionCondition
CenterSpace.NMath.Core..::.MismatchedSizeException Thrown when the signal data (each row) is shorter than this DoubleForward1DFFT instance.
