nlcpy.fliplr

nlcpy.fliplr(m)[source]

Flips array in the left/right direction.

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

Parameters
marray_like

Input array, must be at least 2-D.

Returns
outndarray

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

flipud

Flips array in the up/down direction.

Note

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

Examples

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