Given vertices specified by the vectors xv and yv, and a single point specified by the numbers X and Y, return "true" if the point lies inside (or on the boundary) of the polygon defined by the vertices.
Example:
% The specified point is the center of the unit square: xv = [0 1 1 0]; yv = [0 0 1 1]; X = 0.5; Y = 0.5;
inside(xv,yv,X,Y) -----> true

The test suit only tests points that are inside or outside but not on the boundary of the polygon

Cyclist, this was a pretty tough problem to solve without resorting to Googling a solution or something similar. I ended up with a function that will work for any n-sided polygon. Thanks for the weekend challenge.

Maybe, thinking this problem in topology aspect is useful.
