coifwavf

Coiflet wavelet filter

Syntax

f = coifwavf(wname)

f = coifwavf(wname) returns the scaling filter f associated with the Coiflet wavelet specified by wname. f is a real-valued vector.

Set the Coiflet wavelet name.

wname = 'coif2';

Compute and plot the scaling filter coefficients associated with the Coiflet.

f = coifwavf(wname);
