biorwavf

Parameters

wname :

wavelet name, 'bior1.1' to 'bior6.8'

RF :

synthesis scaling filter

DF :

analysis scaling filter

Description

biorwavf is an utility function for obtaining twin scaling filters of bi-orthogonal spline wavelet including bior1.1, bior1.3, bior1.5, bior2.2, bior2.4, bior2.6, bior2.8, bior3.1, bior3.3, bior3.5, bior3.7, bior3.9, bior4.4, bior5.5 and bior6.8. Although the twin filters have different length, zeros has been fed to keep two filters the same length.

Examples

[RF,DF]=biorwavf('bior3.3');
