As background for others who wanted to try something with the Statistics Toolbox (which I don't have), I suggested a 1D vector of all the image gray level values, grayImage(:), for his "X" in http://www.mathworks.com/matlabcentral/answers/121795#comment_202439. But I couldn't test it for him because I don't have the Stats toolbox.

Empty cluster created at iteration 1.

converged = batchUpdate();
