There are some specific analysis to evaluate The performance of the substitution box (Sbox) such as Linear approximation probability (LAP) just I want code by MATLAB to find LAP for SBOX -(that used in AES algorithm)

What do you mean by this? Can you elaborate or given an example?

There is no question in this, just your need for code. But also, you have not even explained what you mean. What is a linear approximation to a matrix? What does that mean (to you)? When does non linearity have to do with anything in this?
