How do I put this into MATLAB?

3 Heat Equation A common concert in engineering is to determine the steady-state temperature distribution of a thin plate when the temperature around the boundary is known. Let T1, T2, ...,Tg denote the temperature at the corresponding node of the mesh in the figure. The temperature at each interior node is approximately equal to the average of the four nearest nodes (to the left, above, below, and to the right). 0 0 0 0 1 50. 1 50 13 15 14 16 7 18 200 20 2 10 10 10 10 Write a linear system of eight equations with eight unknowns, one for each Ti to find the temperature at each node. Use Matlab to solve the resulting linear system; write your results
