Thanks Janti. You're correct. I fixed it.
26 Jul 2010 kmeans clustering Fully vectorized kmeans algorithm. Fast yet simple (10 lines) Author: Michael 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)'));

lili: I'm not sure what you mean. the format of a raw file does not depend on the complexity of the 3D shape it describes.
28 Jan 2009 Click3dPoint Select a point from a 3D point cloud by clicking on it. Author: Babak Taati

to Jveer:

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

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

Exactly what was needed. Great work.

This is very useful. I need to output the coordinates of the point to use elsewhere, do you know how I can do that? I tried guidata but it didn't work.

thanks,
Kourosh
