function [NcutDiscrete,NcutEigenvectors,NcutEigenvalues] = ncutW(W,nbcluster);
% [NcutDiscrete,NcutEigenvectors,NcutEigenvalues] = ncutW(W,nbcluster);
% 
% Calls ncut to compute NcutEigenvectors and NcutEigenvalues of W with nbcluster clusters
% Then calls discretisation to discretize the NcutEigenvectors into NcutDiscrete
