Need a Matlab code

Sir I am doing M Sc project based on mixed finite element method i need help in solving the numerical problems which was done by matlab

There is definitely not enough information here for anybody to be able to help you.

Also, if this is for your MSc project then you need to at least show us that you've had a try first. That way you can show us where you got stuck and what specifically you need help on rather than just asking us to do your project for you.

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.
