%% 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.
