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)
  
  f =
