11 Dec 2011 Clustering Toolbox The toolbox provides four categories of functions. Author: Janos Abonyi Shay

I have managed to fix a 'bug' in Kmedioid.m, this might help someone some day so here goes:
In line 22 the original code is:
| while prod(max(abs(v - v0))),
This code goes to 0 due to floating point roundoffs quickly, especially for large normalized distance matrices.
My solution:
| while ~isinf(sum(log10(max(abs(v-v0))))),

Hope this helps someone.
