Write a Matlab program that does the following: Make an array x_vals with 300 equally spaced elements, starting at -8 and ending at +8. Calculate y_vals = f(x) = 6 sin x Now add a random value between 0 and 1 (using rand) to each element of y_vals. Now plot x_vals versus y_vals to produce a noisy sinusoidal graph. Make sure you have a good looking graph, as per your class notes (including readable axis labels and a legend). Make professional colour choices, and frame the plot well on the graph. Give it the following title: "A Noisy Sine Wave".
