procedure BiSpectrumVert(const BiSpectrum: TVec; const Spectrum: TVec; Index: Integer; MtxPacked: Boolean);
Compute a part of the bispectrum.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | BiSpectrum | TVec | |
| 2 | Spectrum | TVec | |
| 3 | Index | Integer | start index |
| 4 | MtxPacked | Boolean |
Result: stored in self (calling object)
Remarks:
Compute a single vertical bispectral line (triple product) from Spectrum and place the result in BiSpectrum. The index parameter defines for which frequency you want to compute the triple product. The triple product will computed for one frequency against all others. When used together with RunningAverage method, you can compute the bicoherence. Bicoherence has 1 where a frequency pair is synchronized in phase. Frequency pairs which are unrelated in phase have a zero in the bicoherence matrix.
