WFILT_REMEZ Filters designed using Remez exchange algorithm Usage: [h,g,a]=wfilt_remez(L,K,B) Input parameters: L : Length of the filters. K : Degree of flatness (regularity) at z=-1. B : Normalized transition bandwidth. [h,g,a]=WFILT_REMEZ(L,K,B) calculates a set of wavelet filters. Regularity, frequency selectivity, and length of the filters can be controlled by K, B and L parameters respectivelly. The filter desigh algorithm is based on a Remez algorithm and a factorization of the complex cepstrum of the polynomial. Examples: --------- : wfiltinfo('remez50:2:0.1'); References: O. Rioul and P.
