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 not be a power of two. Size and Complex properties of the calling object 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 IFFTToReal. Look there for more information on FFT parameters and storage requirements.
