Biorthogonal spline wavelet filter
[RF,DF] = biorwavf(W)
[RF,DF] = biorwavf(W) returns the reconstruction (synthesis) and decomposition (analysis) filters associated with the biorthogonal wavelet specified by the string W.
W = 'biorNr.Nd' where possible values for Nr and Nd are
|Nr = 1||Nd = 1 , 3 or 5|
|Nr = 2||Nd = 2 , 4 , 6 or 8|
|Nr = 3||Nd = 1 , 3 , 5 , 7 or 9|
|Nr = 4||Nd = 4|
|Nr = 5||Nd = 5|
|Nr = 6||Nd = 8|
The output arguments are filters.
RF is the reconstruction filter.
DF is the decomposition filter.
Return the biorthogonal spline wavelet scaling filters with 2 vanishing moments.
wname = 'bior2.2'; [RF,DF] = biorwavf(wname);
