Summary
The inverse FFT from complex to complex.
Class
TDenseMtxVec
Declaration
Function IFFT(Vec: TMtxVec; VecIndex, Index, Len: integer; NoScale: boolean = False): TMtxVec;
Description
Calculate the inverse 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 vector 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 TVec.IFFT. Look there For more information on FFT parameters and storage requirements.
