Matrix.IFFT Method

The inverse FFT from complex to complex.

Pascal
function IFFT(const Vec: TMtxVec; VecIndex: integer; Index: integer; Len: integer; NoScale: boolean = False): TMtxVec; overload;

Calculate the inverse 1D FFT from Vec elements [VecIndex]..[VecIndex+Len-1] and store the results in the calling object elements [Index]..[Index+Len-1]. The Len parameter must be the power of two. Size and Complex properties of the calling Matrix must be set explicitly. An exception is raised if ConditionCheck is True and array borders are overrun.

This is the indexed version of the FFT routine IFFT. Look there For more information on FFT parameters and storage requirements.
