Use rgb2gray() from the Image Processing Toolbox. Then kmeans() from the Statistical Toolbox. Here's a demo: http://www.mathworks.com/products/demos/image/color_seg_k/ipexhistology.html

Sorry I don't understand the language. I don't know what to click, and it started spewing out a bunch of stuff that I didn't know what it was into the command window. It went on for several minutes and I couldn't stop it, not even with control-C. I had to go into task manager to finally kill off MATLAB.
I suggest you try normal debugging operations to figure out what's going on.

Never mind, my program works correctly only when clustering image It takes a long time.
I need, show my output.
I have output in cell.
for example Z= {1438x1} {5800x1} {425x1} {45x1}
in Z{1} is [48] [ 55] [46] ......
in Z{2} is [78] [ 89] [94].....
in Z{3} is [ 120] [ 134] [ 158]...
in Z{4} is [ 210] [ 248] [255].....
how to convert cell, so I could see it as a image.
