03 Jul 2010 KMeans Segmentation - MEX Given N data elements of R dimensions (N x R matrix), it segregates the n elements into k clusters Author: Ahmad

Thanks Mitsu. I'll make that fix.

Plus the kmeans comes with the statistics toolbox, which I didn't have access to. So I thought might be useful for other ppl.

@Henry
Warning added and the no. of nodes can be set by WARNING_CONNECTING_NODES_LENGTH .... which defaults to 20.

I have done this since an NP-hard problem's actual computability would vary from machine to machine

Very useful for my grayscale experiments!

The code make my matlab crash because of memory violation.
I am using mac os X, and apparently mxUNIT32_CLASS matlab type do not fit standard unsigned long c type. So I changed "data_idxs" into double* type rather than unsigned long* and everything works fine. Btw we one should use this code rather than the matlab kmeans function? Your code doesnt look to go faster or bring any more options.

Looking good! The utilities file was a nice surprise. :)
