initial-value-problem code snippets in matlab

consider the initial value problem 𝑦’ = 𝑡 2 + 𝑐𝑜𝑠 𝑦, 𝑦(0) = 0. use matlabto plot the solution for 0 ≤ t ≤ 1 and find the approximate value of y(1). in matlab

y'' + 3y' + 2y = h(t), y(0) = 1, y'(0) = 0, h(t) = u_π(t), if 0 ≤ t ≤ 10 0, if t > 10. in matlab
