# numpy.tile

`numpy.``tile`(A, reps)

  Construct an array by repeating A the number of times given by reps.

  Parameters: | A : array_like The input array. reps : array_like The number of repetitions of A along each axis.
  Returns: | c : ndarray The output array.

  `repeat`

  Notes

  If reps has length d, the result will have dimension of max(d, A.ndim).

  If A.ndim < d, A is promoted to be d-dimensional by prepending new axes. So a shape (3,) array is promoted to (1,3) for 2-D replication, or shape (1,1,3) for 3-D replication. If this is not the desired behavior, promote A to d-dimensions manually before calling this function.

  If A.ndim > d, reps is promoted to A.ndim by pre-pending 1’s to it. Thus for an A of shape (2,3,4,5), a reps of (2,2) is treated as (1,1,2,2).

  Examples

      >>> a = np.array([0, 1, 2])
      >>> np.tile(a, 2)
      array([0, 1, 2, 0, 1, 2])
      >>> np.tile(a, (2, 2))
      array([[0, 1, 2, 0, 1, 2],
             [0, 1, 2, 0, 1, 2]])
      >>> np.tile(a, (2, 1, 2))
      array([[[0, 1, 2, 0, 1, 2]],
      <BLANKLINE>
             [[0, 1, 2, 0, 1, 2]]])

      >>> b = np.array([[1, 2], [3, 4]])
      >>> np.tile(b, 2)
      array([[1, 2, 1, 2],
             [3, 4, 3, 4]])
      >>> np.tile(b, (2, 1))
      array([[1, 2],
             [3, 4],
             [1, 2],
             [3, 4]])
