Thanks Janti. You're correct. I fixed it.

26 Jul 2010 kmeans clustering Fully vectorized kmeans algorithm. Fast yet simple (10 lines) Author: Mo Chen

This is a really nice function.

As Fen Xie pointed out, it sometimes returns empty clusters (esp if you set k, the desired number of clusters too high compare to the size of you data).

The solution is easy though. You only need two extra lines of code to get rid of the empty clusters:

% 1- dicsard empty clusters
centers = centers(:, unique(labels));

% 2- re-assign labels
[~,labels] = max(bsxfun(@minus,centers'*X,0.5*sum(centers.^2)'));

to Jveer:

>> set(gcf,'WindowButtonDownFcn','');

better: change ClickA3DPoint.m so it returns a handle to the figure and use that instea of gcf.
