numpy.flip(m, axis)
[source]
Reverse the order of elements in an array along the given axis.
The shape of the array is preserved, but the elements are reordered.
New in version 1.12.0.
Parameters: |
m : array_like Input array. axis : integer Axis in array, which entries are reversed. |
---|---|
Returns: |
out : array_like A view of |
flip(m, 0) is equivalent to flipud(m). flip(m, 1) is equivalent to fliplr(m). flip(m, n) corresponds to m[...,::-1,...]
with ::-1
at position n.
>>> A = np.arange(8).reshape((2,2,2)) >>> A array([[[0, 1], [2, 3]],
>>> flip(A, 0) array([[[4, 5], [6, 7]],
>>> flip(A, 1) array([[[2, 3], [0, 1]],
>>> A = np.random.randn(3,4,5) >>> np.all(flip(A,2) == A[:,:,::-1,...]) True
