`numpy:array_equiv`

Signature

def array_equiv ( a1 , a2 )

Returns True if input arrays are shape consistent and all elements equal.

Shape consistent means they are either the same shape, or one input array can be broadcasted to create the same shape as the other one.

import numpy as np
np.array_equiv([1, 2], [1, 2])
np.array_equiv([1, 2], [1, 3])

✓

Showing the shape equivalence:

np.array_equiv([1, 2], [[1, 2], [1, 2]])
np.array_equiv([1, 2], [[1, 2, 1, 2], [1, 2, 1, 2]])

✓

np.array_equiv([1, 2], [[1, 2], [1, 3]])
