The Computational Tool The Improved Euler Method improves upon the standard euler method by using a trapezoid to approximate the integral )t, rather than a rectangle. The goal is the same: to approximate a solution to the first order initial value problem: dy(t) y(to) yo = at N +1 evenly spaced points: to, t,..., tv. The improved Euler Method is described by the iteration The vector yz is meant to approximate y(t). 1. (20 points) Write a pseudocode for the Improved Euler timestepping method. 2. (40 points) Implement your Improved Euler code as a Matlab function names ieuler.m for solving ordinary differential equations, using the following input and outputs Input . The vector-valued function of two variables: f. An initial condition vector yo- . A starting time to . An ending time tv. . The number of timesteps, N Output . A matrix y whose columns approximate the solution y(t) for each value to, t., tv Your code should begin: function y - ieuler(func, yo, to, tf,Nt)
