finite difference 2d surface insulated

hello all

i have a 2d Finite Difference problem.

A surface with insulated up side. I want to have a MATLAB code to give me the Temperature of node 5 (T5) by using FD method;

Please solve this by MATLAB.

for each data you need for solving , assume it a number you want for dimension and h and T and others.

I just want to understand how should solve and how is this problem code.

So please assume the initial and boundary conditions everything ou think is good.

Thank you all
