use matlab to solve the question

Write software code to compute and plot the (a) convex hull and (b) sub (convex) hulls for the following two dimensional data. Use any convex (sub) hull computing algorithms of your choice. If you use open source codes clearly explain the algorithms used by the codes. 3. (x,y) data co-ordinates: (1,1), (0.5,3), (1.5,4), (3,3), (4,0.5), (42.5), (5.5,2.5),(6,1), (7,2), (5.5,4.5) O o
