functionwavRevBiorSpline
Reverse biorthogonal spline wavelet filters
Information
This function generates the biorthogonal spline wavelet filters, where Nr is the order of the reconstruction filters, and Nd the order of the decomposition filters.
Usually, lodFd and hidFr are used for decomposition, and lorFr and hirFd are used for reconstruction.
Available orders of biorthogonal wavelet filters
| Nd | Nr |
| 1 | 1, 3, 5 |
| 2 | 2, 4, 6, 8 |
| 3 | 1, 3, 5, 7, 9 |
| 4 | 4 |
| 5 | 5 |
| 6 | 8 |
