FourierInverse2D(Complex, Int32, Int32, FourierOptions) Method

Applies the inverse Fast Fourier Transform (iFFT) to two dimensional sample data.

Syntax

public static void Inverse2D(
	Complex[] spectrumRowWise,
	int rows,
	int columns,
	FourierOptions options = FourierOptions.Default
)

spectrumRowWise Complex: Sample data, organized row by row, where the iFFT is evaluated in place
rows Int32: The number of rows.
columns Int32: The number of columns.
options FourierOptions (Optional): Fourier Transform Convention Options.

Remarks

Data available organized column by column instead of row by row can be processed directly by swapping the rows and columns arguments.
