Coiflet wavelet filter


F = coifwavf(W)


F = coifwavf(W) returns the scaling filter associated with the Coiflet wavelet specified by the character vector W where W = 'coifN'. Possible values for N are 1, 2, 3, 4, or 5.


% Set coiflet wavelet name. 
wname = 'coif2'; 

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

f =
