Antonis, I can speculate that the problem lies in the input data you are using (too few unique data points). Can you send me your code and dataset, so I can do some debug?

12 Jul 2014 MatlabBGL MatlabBGL provides robust and efficient graph algorithms for Matlab using native data structures. Author: David Gleich

10 Dec 2013 Information Theory Toolbox Functions for Information theory, such as entropy, mutual information, KL divergence, etc Author: Mo Chen

Very useful and efficient toolbox, thank you. However, there is a bug in the nmi.m. last sentence should read:
z = sqrt((MI/Hx)*(MI/Hy));
Output variable is "z" and not "v". But this is obvious a typo, so it does not influence my rating.

27 Aug 2013 K-medoids K-medoids clustering algorithm Author: Mo Chen

Very compact and efficient coding. Nice job!
However, there is an error when k=1. I suggest to add the third parameter (dimension) to the calls of function min:
(Line 8): [~, label] = min(D(randsample(n,k),:),[],1);
(Line 11): [~, label] = [~, index] = min(D*sparse(1:n,label,1,n,k,n),[],1);

17 Oct 2014 Modified & Generalized Dunn's index An implementation of Modified and Generalized Dunn's index for internal cluster validation. Author: Nejc Ilc Antonis Alexiadis

the EMST option doesn't work(at least for me) i get the error Error using cgprechecks (line 41)
Not enough unique points specified.

Error in delaunayn (line 48)
cgprechecks(x, nargin, cg_opt);

Error in graph_EMST (line 38)
DT=delaunayn(data);

Error in graph_create (line 82)
[G,d] = graph_EMST(data,[]);

Error in indexDNg (line 66)
G=graph_create(data,labels,graph_type,options);
