			function [ F ] = gsp_filterbank_matrix(G,g,param )
			%GSP_FILTERBANK_MATRIX Create the matrix of the filterbank frame
			% Usage: F = gsp_filterbank_matrix(G, g param );
			% F = gsp_filterbank_matrix(G,g);
			%
			% Input parameters:
			% G : Graph
			% g : Filters
			% param : Structure of optional parameter
			% Output parameters:
			% F : Frame
			%
			% This function create the matrix associated to the filterbank g. The
			% size of the matrix is MN x N, where M is the number of filters.
			%
			% param a Matlab structure containing the following fields:
			%
			% param.verbose : 0 no log, 1 print main steps, 2 print all steps.
			% By default, it is 1.
