jax.numpy.fliplr

jax.numpy.fliplr(m)[source]

Flip array in the left/right direction.

LAX-backend implementation of fliplr(). Original docstring below.

Flip the entries in each row in the left/right direction. Columns are preserved, but appear in a different order than before.

Parameters

m (array_like) – Input array, must be at least 2-D.

Returns

f – A view of m with the columns reversed. Since a view is returned, this operation is \(\mathcal O(1)\).

Return type

ndarray

See also

flipud()

Flip array in the up/down direction.

rot90()

Rotate array counterclockwise.

Notes

Equivalent to m[:,::-1]. Requires the array to be at least 2-D.

Examples

>>> A = np.diag([1.,2.,3.])
>>> A
array([[1.,  0.,  0.],
       [0.,  2.,  0.],
       [0.,  0.,  3.]])
>>> np.fliplr(A)
array([[0.,  0.,  1.],
       [0.,  2.,  0.],
       [3.,  0.,  0.]])
>>> A = np.random.randn(2,3,5)
>>> np.all(np.fliplr(A) == A[:,::-1,...])
True
