ChirpFFTFourierTransformation2D Method

Performs an two dimensional FFT of arbitrary length by the chirp method. Use this method only if no other FFT is applicable.

Namespace: Altaxo.Calc.Fourier
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)

Syntax

public static void FourierTransformation2D(
	IMatrix<double> matrixRe,
	IMatrix<double> matrixIm,
	FourierDirection direction
)

matrixRe IMatrixDouble: Matrix of thre real part of the values to transform.
matrixIm IMatrixDouble: Matrix of thre imaginary part of the values to transform.
direction FourierDirection: Direction of Fourier transform.

Remarks

This function first performs a FFT on all columns of the matrix, and then transforms all rows of the resulting matrix.
