numpy.fliplr

numpy.fliplr(m)

Left-right flip.

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.

Returns:

f : ndarray

A view of m with the columns reversed. Since a view is returned, this operation is .

See also

flipud

Flip array in the up/down direction.

rot90

Rotate array counterclockwise.

Notes

Equivalent to A[::-1,...]. Does not require the array to be two-dimensional.

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(numpy.fliplr(A)==A[:,::-1,...])
True
