createVector

CREATEVECTOR Create a vector from two points.

   V12 = createVector(P1, P2)
   Creates the vector V12, defined as the difference between coordinates
   of points P1 and P2.
   P1 and P2 are row vectors with ND elements, ND being the space
   dimension.

   If one of the inputs is a N-by-Nd array, the other input is
   automatically repeated, and the result is N-by-Nd.

   If both inputs have the same size, the result also have the same size.
