function [ G ] = gsp_update_weights( G, W )
%GSP_UPDATE_WEIGHTS update weight matrix of the graph G
% Usage: G = gsp_update_weight( G, W );
%
% Input parameters
% G : Graph
% W : W new weight matrix
% Output parameters
% G : Graph
%
% This function will update the weight of graph and recompute the
% Laplacian the new Laplacian. It will also recompute the value G.lmax*
% if it is present in the graph.
%
% For now this function does not recompute the Fourier basis!
%
% Example:
%
% G.W = Wnew;
% G = gsp_graph_default_parameters( G );
%
%
% See also: gsp_graph_default_parameters gsp_graph
