Modify lab04ex2.m so that it solves (l4.7) using euler’s method with n = 1000 in the interval 0 ≤ t ≤ 50 (use the file euler. m from lab 3 to implement euler’s method; do not delete the lines that implement ode45). let [te, ye] be the output of euler, and note that ye is a matrix with two columns from which the euler’s approximation to y(t) must be extracted. plot the approximation to the solution y(t) computed by ode45 (in black) and the approximation computed by euler (in red) in the same window (you do not need to plot v(t) nor the phase plot). are the solutions identical? comment. what happens if we increase the value of n?
