Write a MATLAB code to solve the following boundary value problem using the Finite Difference Method: Vu(x,y) = 0 on the square 0 < x < 1, 0 < y < 1 subject to the boundary conditions u(1,y) = y u(x, 1) = 2x 0.5| = 0 at x = 0 = 0 at y = 0.| A code to solve the same problem using MATLAB's Finite Element Method toolbox has been provided for you to compare your solution against. You should present your finite difference solution in the form of dotted contour lines overlaying the finite element solution, in a figure like so: 1 0.9 0.8 0.7 0.6 > 0.5 0.4 Solid: FEM, Dashed: FDM 1 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.3 0.2 0.2 0.1 0.1 0 0 02 04 06 08
