Please just send me as Matlab codes!!!

Solve, d^2y/dt^2 + t dy/dt - 3y = 4.2t on (0, 1) with y(0) = 0, y(1) = 1.9 Shooting method with Euler scheme. You may assume the initial slopes to be z_1 = 0.8, z_2 = 1, h = 0.25. Finite Difference method with h = 0.25. Compare your results graphically with the exact solution y = t^3 + 0.9t
