function  [h,g,rh,rg]=remezflt(L,K,B)

%REMEZFLT     Generates orthonormal wavelet filters based on the Remez
%	      exchange algorithm.
%
%	      [H,G,RH,RG] = REMEZFLT(L,K,B) returns a set of wavelet
%	      filters. You can control regularity, frequency selectivity,
%	      and length of the filters. It works performing a factorization
%	      based on the complex cepstrum of the polynomial returned by
%	      REMEZWAV.
%
%	      L is the length of the filters. K is degree of flatness at
%	      z=-1. B is the normalized transition bandwidth.

%	      See also: REMEZWAV, FC_CCEPS.
