numpy.flipud(m)
[source]
Flip array in the up/down direction.
Flip the entries in each column in the up/down direction. Rows are preserved, but appear in a different order than before.
Parameters: |
m : array_like Input array. |
---|---|
Returns: |
out : array_like A view of |
Equivalent to m[::-1,...]
. Does not require the array to be two-dimensional.
>>> A = np.diag([1.0, 2, 3]) >>> A array([[ 1., 0., 0.], [ 0., 2., 0.], [ 0., 0., 3.]]) >>> np.flipud(A) array([[ 0., 0., 3.], [ 0., 2., 0.], [ 1., 0., 0.]])
>>> A = np.random.randn(2,3,5) >>> np.all(np.flipud(A) == A[::-1,...]) True
>>> np.flipud([1,2]) array([2, 1])
