%  
% 1) demo_simulatedDataset1.m <-- This demo illustrates the NMF_QMV hyperspectral 
%    unmixing algorithm operating in simulated Dataset1 (SCENARIO:  non pure 
%    pixels, various number of endmembers and noise level)
% 
% 2) demo_unmixing_Rcuprite_TERRAIN.m  <-- This demo illustrates the NMF_QMV 
%    hyperspectral unmixing  algorithm operating in Rcuprite image and TERRAIN image.
% 
% 3) GenerateHSIFromTerrain.m <-- This script illustrates the procudure to generates 
%    a simulated image from TERRAIN data.
% 
% 4) NMF_QMV.m <-- hyperspectral unmixing method based on Nonnegative Matrix 
%    Factorization via Quadractic Minimum Volume (NMF_QMV)
% 
% 5) nmf_qmv_subspace.m <-- NMF-QMV working in a dimension-reduced space.
