dpnp.flipud

Reverse the order of elements along axis 0 (up/down).

For a 2-D array, this flips the entries in each column in the up/down direction. Rows are preserved, but appear in a different order than before.

For full documentation refer to numpy.flipud.

Parameters:: m ({dpnp.ndarray, usm_ndarray}) -- Input array.
Returns:: out -- A view of m with the rows reversed.
Return type:: dpnp.ndarray

Examples

>>> import dpnp as np
>>> A = np.diag(np.array([1., 2., 3.]))
>>> A
array([[1.,  0.,  0.],
       [0.,  2.,  0.],
       [0.,  0.,  3.]])
>>> np.flipud(A)
array([[0.,  0.,  3.],
       [0.,  2.,  0.],
       [1.,  0.,  0.]])

>>> A = np.random.randn(2, 3, 5)
>>> np.all(np.flipud(A) == A[::-1, ...])
array(True)

>>> np.flipud(np.array([1, 2]))
array([2, 1])
