## @deftypefn {Function File} {@var{vect} = } createVector (@var{p1}, @var{p2})
## 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.
