orthfilt

orthogonal wavelet filter set

Calling Sequence

[Lo_D,Hi_D,Lo_R,Hi_R]=orthfilt(w)

Parameters

w
: scaling filter
Lo_D
: lowpass analysis filter
Hi_D

Description

orthfilt is an utility function for obtaining analysis and synthesis filter set of given orthogonal wavelets including haar, daubechies, coiflets and symlets.

Examples

w=dbwavf('db2');
[lo_d,hi_d,lo_r,hi_r]=orthfilt(w);
