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.

Thx for your code. But I double checked that your likelihood calculation is wrong!

Thanks for you code. It is great! But to address my problem, I need every Gaussion function shares exactly the same width. Is that possible or which part I need to amend?

When I use this to find peaks it always displays a zoomed in area for the fit. How can I show the entire plot with the fits?
