If Octave is not possible I also run MATLAB as a backup for the class

ave lintenratinn3 m Write an Octave program that uses the composite Simpson's rule to ap- proumate the integral dz using 2, 4, 8, and 16 intervals (i.e. 3, 5, 9, and 17 points). Evaluate the integral analytically, and plot the log of the absolute value of the error in the approximations vs. the log of Az. What do you observe? If the resulting plot is linear, find its slope
