TMtxVec *IFFTToReal(TMtxVec *Vec, int VecIndex, int Index, int Len, bool NoScale = false);
The inverse FFT from complex to real.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec | TMtxVec * | |
| 2 | VecIndex | int | |
| 3 | Index | int | |
| 4 | Len | int | |
| 5 | NoScale = false | bool |
Remarks:
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 TMtx::Complex properties of the calling object must be set explicitly. An exception is raised if TMtx::ConditionCheck is True and array borders are overrun.
This is the indexed version of the FFT routine TVec::IFFTToReal. Look there for more information on FFT parameters and storage requirements.
