Installation Notes :

1) After you unzipped the files to mydir, 
   put the Current Directory in Matlab to mydir

2) In the matlab command prompt,

	type demoNcutClustering to see a demo

		or...
 
 	type main to initialize the paths to subfolders

3) You can now try any of the functions

The files were tested under matlab 6.5

Top level functions:

ncutW:  Given a similarity graph "W", computes Ncut clustering on the graph into "ncCluster" groups;
        NcutDiscrete = ncutW(W,nbCluster);

Use demo.m to see how to use the clustering function.
