Objective: To demonstrate knowledge of how to use the functions related to regression in Matlab (10 pts) You should work on this task individually Write a Matlab script that will find the best-fit 7th order polynomial for data points generated by a sine function. To create the data, the first two lines of your script should be x - linspace (0,4 pi,10); y = sin (x) ; Your script should fit this x-y data using polyfit, and then plot the data and the best-fit line (as a smooth curve). The resulting plot should look like this: Figure 5 File Edit View Insert Tools Desktop Window Help 1.5 0.5 0.5 -1 2 4 6 8 10 12 Submit your script as an m-file. You do not have to submit a figure; it is included here just to give you an idea what the output should be
