Its what you would get if you explicitly reshaped vector to be 1x3 instead of 3x1. Returns a true division of the inputs element-wise. Python element wise division.

Moreover division by zeroalways yields zero in integer arithmetic. The numpydivide is a universal function ie supports several parameters that allow you to optimize its work depending on the specifics of the algorithm.
