Octave (or MATLAB) / operator

I wonder what / operator does in Octave. (I am not sure whether it works the same way in MATLAB)

V = [1; 2; 3]

then

1 / V = [0.071429 0.142857 0.214286]

I know that ./ operator does element-wise division of vectors or matrices. Then what does / operator do?

This behavior is described in the documentation:

x / y

Right division. This is conceptually equivalent to the expression

(inverse (y') * x')'

but it is computed without forming the inverse of y’.

If the system is not square, or if the coefficient matrix is singular, a minimum norm solution is computed.

MATLAB has exactly the same behavior, see its documentation.
