Have a look at http://stackoverflow.com/questions/25019840/neighboring-gray-level-dependence-matrix-ngldm-in-matlab. It includes Matlab code.

I've already checked this code..But it returnes error:" first prompted subs should be positive integers"... So, I'm confused...

Please post the code and the line that returned the error.
