Both methods `array_equal(~)`

and `array_equiv(~)`

are similar in that they both return a single Boolean when all the elements in the given arrays are equal pair-wise.

The key difference is that `array_equal`

returns True when the shape of the arrays exactly match, whereas `array_equiv`

will also return True if the one array can be broadcasted to take on the same shape.

Here's an example:

```

NumPy | array_equal method

Numpy's array_equal(~) takes in two arrays and returns True if they have the same shape and elements.

NumPy | array_equiv method

Numpy's array_equiv(~) takes in two arrays and returns True if they have consistent shape and the same elements.
