Character string of Hilbert wavelet pair, see acceptable
names below (e.g., |
Simple switch statement selects the appropriate HWP. There are
two parameters that define a Hilbert wavelet pair using the notation
of Selesnick (2001,2002), K and L. Currently, the only
implemented combinations (K,L) are (3,3), (3,5), (4,2) and
(4,4).
List containing the following items:

length of the wavelet filter |
h0,g0 |
low-pass filter coefficients |
h1,g1 |
high-pass filter coefficients |
