3. Write a Matlab function called AB4 that solve (1) using four-step Adams-Bashforth method. You may use your textbook to get the coefficients. Use this method to solve the IVP (2) with N 20,50, 100 Call y6, y7, y8, the three results and plot the three solutions on the same graph. Notice: be careful on how to evaluate the first steps ! Make a loglog plot of absolute error at t1 versus the number of intervals for all three methods on the same plot. Compare the solution at t 1 with the exact solution at t 1. Create Err2 a vector that stores the absolute error of the three solutions at t-1. Comment
