Broadcast any number of arrays against each other.
Parameters: | `*args` : arrays
|
---|---|
Returns: | broadcasted : list of arrays
|
Examples
>>> x = np.array([[1,2,3]])
>>> y = np.array([[1],[2],[3]])
>>> np.broadcast_arrays(x, y)
[array([[1, 2, 3],
[1, 2, 3],
[1, 2, 3]]), array([[1, 1, 1],
[2, 2, 2],
[3, 3, 3]])]
Here is a useful idiom for getting contiguous copies instead of non-contiguous views.
>>> map(np.array, np.broadcast_arrays(x, y))
[array([[1, 2, 3],
[1, 2, 3],
[1, 2, 3]]), array([[1, 1, 1],
[2, 2, 2],
[3, 3, 3]])]
