WFILT_SYMORTH - Symmetric nearly-orthogonal and orthogonal nearly-symmetric

Usage

[h,g,a] = wfilt_symorth(N);

Description

[h,g,a]=wfilt_symorth(N) with \(N\in {1,2,3}\) returns orthogonal near-symmetric (\(N==1\)) and symmetric near-orthogonal (\(N==[2,3]\)) wavelet filters from the reference.

The filters exhibit a coiflet-like behavior i.e. the scaling filter has vanishing moments too.

Examples:

wfiltinfo('ana:symorth2');

wfiltinfo('syn:symorth2');
