Kelly Cohen

If you have not looked into it yet, a good place to start is using kmeans and Fuzzy cmeans clustering to get you a better insight into a desirable objective function.. Through MATLAB, these are simple commands which minimize the least square of the euclidean distances between cluster center and points belonging to that specific cluster.

Mahamad Nabab Alam

kmeans clustering available in MATLAB can be used for it.
