MATLAB! please type out the Matlab code for this problem. Thank you in advance!!

Problem 3: Consider following initial value problem: - exp(-2)-2y dy y(0)-1/10 where the exact solution is >(C)-0.lexp-2)+texp(-21) exp(-2t) +te a) Write a MATLAB code to numerically solve the initial value problem over the interval [0, 2] using Euler's method with a fixed sample period, At 0.2. Calculate the error curve for the following sample periods 1-02, 0.1 and 0.05. b) Repeat part a) using Heun's method and the Runge-Kutta method
