Finding the area inside a convex hull

This quick video answers a question about finding the area of the smallest polygon that covers a set of points. It is a chance to use a few commands in MATLAB to simplify a script. Here is the code that will be discussed.
 x1 = rand(1,10);
 y1 = rand(1,10);

 vi = convhull(x1,y1);

 axis equal
 hold on
 fill ( x1(vi), y1(vi), 'r','facealpha', 0.5 ); 
 hold off
