Daubechies wavelet filter.

Syntax

F = dbwavf(W)

Description

F = dbwavf(W) returns the scaling filter associated with Daubechies wavelet specified by the string W where W = 'dbN'. Possible values for N are: 1, 2, 3, ..., 45.

Examples

% Set Daubechies wavelet name. 
wname = 'db4'; 

% Compute the corresponding scaling filter. 
f = dbwavf(wname)
