That's about all we can say with what you gave us. We'd need specifics to provide any more code. There's a lot you can do with MATLAB but unless we know what it is, we can't offer advice other than to look at this link: http://www.mathworks.com/matlabcentral/answers/8026-best-way-s-to-master-matlab
