Good code!!! It works very well.

However, I found a bug. In Matlab R2013
for k=5:15
[W,M,V,L] = EM_GM(Data',k,0.001,1000,1,[]);
end
For certain k, it came out with error:
Attempted to access maxy(1); index out of bounds because numel(maxy)=0.

I noticed that some value in M were set as Nan.

However, for the same data in Matlab 7.1 it works perfectly fine.

Hi,
Thank you so much for this tool
Is it possible to save clusters membership?

Thanks
Moran

Hi
thank you so much for your care Yashodhan.

I did so, but with transpose of X, same error occurred!!
