What is the difference between Matlab built-in 'kmeans' and the k-means method behind imsegkmeans?

May I acces the code/method inside imsegkmeans?

I've seen it goes to: "[Label,NormCen] = images.internal.ocvkmeans(X,k,NumAttempts,MaxIterations,Threshold);" at line 37 of images.internal.algkmeans() function but I can't go deeper and enter ocvkmeans.

What is the difference between Matlab built-in kmeans function (which uses a Matlab accessible implementation) and this ocvkmeans ?

Thanks,

Note that MATLAB does not have a built-in kmeans. There is a kmeans utility in the stats toolbox however.

But asking what is in compiled code is not possible to know, since unless you work for the MathWorks, you cannot see the code.
