The figure below is an example profile of a man. Instead of the profile, you can also use a unique (different to every one else's) profile (e.g. car, boat) of your own from any other source.
a) Include the original photograph of your selected profile with your assignment. Trace your drawing on a graph paper. For convenience you can rotate the given profile.
b) Locate 20 points on the profile. You should select more points where the profile is more curvy, and few points where the profile is almost linear. Display these points in MATLAB output and on MATLAB chart with color blue but no lines to join them.
c) You will use MATLAB polyfit and polyval functions to find one polynomial with all points. Now plot the profile with your fitted polynomial; you should plot more points on the polynomial in this case. Use a different color.
d) Try different numbers of points from your tracing for polyfit and different numbers of points for polyval to plot them. Show at least five different attempts. You will plot these 5 attempts using 5 different colors. Make these attempts in such as way that the best plot looks as much alike as possible to the original profile given.
