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:

highpass analysis filter

Lo_R:

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);
