In this exercise, you will learn to picture what different orders of convergence mean and experiment with the effect of round-off errors. We know from the lecturesotes that the forward difference quotient converges linearly, and the central difference quotient Death) f-h) converges quadratically to f"(t) as 0 if f is smooth enough and no a) Write a function d-D_F(f,x,h) in Matlab that computes the forward b) Write a function d-D_C(f,x,h) in Matlab that computes the central round-off errors occur difference quotient of f with step-size h at the point x. quotient of f with step-size h at the point x. c) Write a script diff test in Matlab which uses the functions from tasks a) and b) to plot the errors In this exercise, you will learn to picture what different orders of convergence mean and experiment with the effect of round-off errors.
