Until then, no one can answer this completely vague question. You might as well say "I need MATLAB to analyze my data. Someone send me the code to do that." It's totally unanswerable, except to say that you need to define/explain your problem better, which is not the answer you want but the only one we could give, given the complete lack of any explanation of your problem.
