# numpy.broadcast_arrays

`numpy.``broadcast_arrays`(*args)

  Broadcast any number of arrays against each other.

  Parameters: | `*args` : arrays The arrays to broadcast.
  Returns: | broadcasted : list of arrays These arrays are views on the original arrays. They are typically not contiguous. Furthermore, more than one element of a broadcasted array may refer to a single memory location. If you need to write to the arrays, make copies first.

  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]])]
