How to implement vector quantization after calculating MFCC?

I have a sample signal, and I computed MFCC using this code .Now I have an array of 1225x12 size, where there are 12 coefficients for 1225 frames. Now I want to test another signal against this sample, and use vector quantization for this.I have this code , but cannot quite understand what to do. It takes data vectors as input,but I have a matrics. Do I convert it into a vector in some way? And how do I determine if two arrays match?
