This page brings together a variety of resources for performing cluster analysis using Matlab. The links are divided into two sections: first, my own Matlab code (.m files) for a variety of clustering algorithms and related utility functions, and second, a list of external links to other toolboxes. If you know of other sites that ought to be included, drop me a note. Everything listed is free (some under GNU licensing), except for the Mathworks toolboxes. Everything works with Version 5, some with earlier versions too.

Note: This page is quite old, so some links may be broken. I'll try and update it one day...

Zipped .m files for clustering:

My Clustering toolbox

 

(Last updated December 2000)

Includes k-means, hierarchical (single-, complete- and mean-linkage), EM for Gaussian Mixture Models, fuzzy c-means, and a demo. Also includes some utilities (for Rand index, data generation, PCA plots etc.). Please Note: some functions also require the Netlab toolbox to be installed (see below).
