protected void GetResultCentered(
	IMatrix<double> matrix,
	Func<double, double, double> resultantEval
)

Parameters

matrix  IMatrixDouble
The matrix to accomodate the result. Can have the dimensions NumberOfRowsxNumberOfColumns or less, but not more.
resultantEval  FuncDouble, Double, Double
A function that takes the real part and the imaginary part of one Fourier transformation point and returns the requested output value.
Exceptions
ExceptionCondition
InvalidOperationExceptionBefore getting any result, you must execute the Fourier transformation first (by calling Execute).
