VECTORS2D Description of functions operating on plane vectors.

   A vector is defined by its two cartesian coordinates, put into a row
   vector of 2 elements:
   V = [vx vy];

   Several vectors are stored in a matrix with two columns, one for the
   x-coordinate, one for the y-coordinate.
   VS = [vx1 vy1 ; vx2 vy2 ; vx3 vy3];
