`numpy:broadcast_to`

Signature

def broadcast_to ( array , shape , subok = False )

Broadcast an array to a new shape.

array : array_like: The array to broadcast.
shape : tuple or int: The shape of the desired array. A single integer i is interpreted as (i,).
subok : bool, optional: If True, then sub-classes will be passed-through, otherwise the returned array will be forced to be a base-class array (default).

broadcast : array: A readonly view on the original array with the given shape. It is typically not contiguous. Furthermore, more than one element of a broadcasted array may refer to a single memory location.

: ValueError: If the array is not compatible with the new shape according to NumPy's broadcasting rules.

import numpy as np
x = np.array([1, 2, 3])
np.broadcast_to(x, (3, 3))
