[FIXED] Numpy cross product matrix function

Issue

Is there a Numpy built-in function that returns a cross product matrix?

That is:

>>> cross_product_matrix_function([1, 2, 3])
array([[ 0, -3,  2],
       [ 3,  0, -1],
       [-2,  1,  0]])

Solution

For 3x3 matricies:

import numpy as np

I = np.eye(3)

def cross_product_matrix_function(m):
    return np.cross(I, m)

print(cross_product_matrix_function([1, 2, 3]))
