mars.tensor.
fliplr
Flip tensor 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.
m (array_like) – Input tensor, must be at least 2-D.
f – A view of m with the columns reversed. Since a view is returned, this operation is \(\mathcal O(1)\).

flipud
Flip array in the up/down direction.
rot90
Rotate array counterclockwise.
Notes
Equivalent to m[:,::-1]. Requires the tensor to be at least 2-D.
Examples
>>> import mars.tensor as mt
>>> A = mt.diag([1.,2.,3.]) >>> A.execute() array([[ 1., 0., 0.], [ 0., 2., 0.], [ 0., 0., 3.]]) >>> mt.fliplr(A).execute() array([[ 0., 0., 1.], [ 0., 2., 0.], [ 3., 0., 0.]])
>>> A = mt.random.randn(2,3,5) >>> mt.all(mt.fliplr(A) == A[:,::-1,...]).execute() True
