Use MATLAB to implement the finite difference method (FDM) to find the electric potential for the following source-free squared region using 4 x 4 grids. V = 50 V-100 15-10 V-100 V V V-30 V-50 VA V-30 V V 14 A Va V-10 Fig. 2.3: For Task 2.1 Hint: You need to derive by hand expressions of the A and b in equation (2-7) for the problem here. The sizes of A and b are determined by the number of grid points with unknown potentials.
