broadcast_to(array, shape, subok=False)[source]¶
Broadcast an array to a new shape.
array : array_like
The array to broadcast.
shape : tuple
The shape of the desired array.
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.
If the array is not compatible with the new shape according to NumPy’s broadcasting rules.
New in version 1.10.0.
