Why is numpy's einsum faster than numpy's built in functions? http://stackoverflow.com/questions/18365073/why-is-numpys-einsum-faster-than-numpys-built-in-functions 1 loops best of 3 694 ms per loop Outer product np.all np.outer arr_1D arr_1D np.einsum 'i k ik' arr_1D arr_1D True timeit np.outer.. arr_1D arr_1D np.einsum 'i k ik' arr_1D arr_1D True timeit np.outer arr_1D arr_1D 1000 loops best of 3 411 us per loop timeit np.einsum.. Einsum seems to be at least twice as fast for np.inner np.outer np.kron and np.sum regardless of axes selection. The primary..
