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:
"c6", c12", "c18", "c24", "c30";
"d2", "d4", "d6", "d8", "d10", "d12", "d14", "d16", "d18", "d20"; "s4", "s6", "s8", "s10", "s12", "s14", "s16", "s18", "s20".
"bs1.1", "bs1.3", "bs1.5", "bs2.2", "bs2.4", "bs2.6", "bs2.8",
"bs3.1", "bs3.3", "bs3.5", "bs3.7", "bs3.9"
