How can we use Linde Buzo Gray (LBG) algorithm for vector quantization for features extracted from images?

I am trying to construct visual vocabulary, and I have 9 training images, out which I have constructed a matrix of (256x9); where 256 shows the features extracted.

Unfortunately it's not a built-in algorithm so you're going to have to supply the code yourself somehow, either write it yourself (see the FAQ), find it on the File Exchange, or hire someone to write it for you. The chances that someone reading this has heard of that algorithm and has code to hand over to you are pretty small.
