wave.filter.matrix(wavelet="d4", nl=1, nh=1, mix=F, dual=F, even=T, filter.reverse=F)
"d4", "s8"
.
See details below for a list of available wavelets.
(nl+nh)
by
(2*max(nl, nh)+m-2)
matrix,
where
m
is the maximum length of the low-pass and the high-pass filters
(the lengths are usually different for biorthogonal wavelets).
This function is called by
dwt.matrix
. The output of
wave.filter.matrix
is multiplied with an appropriate boundary matrix to obtain the wavelet
transform matrix.
Available orthogonal wavelet filters are:
