Thanks to reply, but in my case i have a feature vector of 6 rows and 6114 columns. so how i can use this code, please give me the solid solution.

I guess you have 6 image analysis measurements for each of 6114 blobs in the image? I can't give you the solid solution - I don't have the Statistics toolbox. Perhaps someone who uses kmeans can help you.

this code return this error also ??? Error using ==> kmeans Too many input arguments.
Error in ==> KmeansI at 21 [cluster_idx cluster_center] = kmeans(ab,nColors,'distance','sqEuclidean', ...

I have an implementation of bisecting k-means algorithm here:

the function is called 'MyKmeans'

Which MATLAB version are you using? The demo probably assumes you have a very recent version.

At the command line, please command
which -all kmeans
and tell us the result.

Ohuh thanks, there ware two function with same name now its working, but now it return me the feature vector like matrix size is 8X6
0.1000 1.0428 0.6896 0.0012 0.0014 0.0001 0.1000 1.0428 0.6896 0.2068 0.1074 0.0305 0.1000 1.0428 0.6896 0.0232 0.0644 0.0025 0.0710 0.7404 0.4896 0.0359 0.0356 0.0031 0.1302 1.3572 0.8975 0.0057 0.0029 0.0002 0 0 0 0.0027 0.0063 0.0004 0.1302 1.3572 0.8975 0.1287 0.1909 0.0496 0.1151 1.2000 0.7935 0.3897 0.3009 0.1020
So is it segmented image if yes then how many regions it have and how i can color the different regions actually the feature vector i give input to the kmeans was LUV components..
