and the MOD and REM documentation:
They both give exactly the same outputs if their input arguments are positive. If their input arguments are negative, then their outputs can differ. This is very easy to demonstrate:
V = -10:0.25:10;
M = [mod(V(:),3),rem(V(:),3)];
plot(V(:),M)
legend('mod','rem','location','best')
You could loosely think of REM as answering the question "what remains after I divide by Q", whereas MOD is completely periodic. Neither is more "correct" or "better", each one is useful in different situtations.
