mxnet.np.rot90¶
-
rot90
(m, k=1, axes=(0, 1))¶ Rotate an array by 90 degrees in the plane specified by axes. Rotation direction is from the first towards the second axis.
- Parameters
m (ndarray) – Array of two or more dimensions.
k (integer) – Number of times the array is rotated by 90 degrees.
axes ((2,) array_like) – The array is rotated in the plane defined by the axes. Axes must be different.
- Returns
y – A rotated view of m.
- Return type
ndarray
Notes
rot90(m, k=1, axes=(1,0)) is the reverse of rot90(m, k=1, axes=(0,1)) rot90(m, k=1, axes=(1,0)) is equivalent to rot90(m, k=-1, axes=(0,1))
Examples
>>> m = np.array([[1,2],[3,4]], 'int') >>> m array([[1, 2], [3, 4]], dtype=int64) >>> np.rot90(m) array([[2, 4], [1, 3]], dtype=int64) >>> np.rot90(m, 2) array([[4, 3], [2, 1]], dtype=int64) >>> m = np.arange(8).reshape((2,2,2)) >>> np.rot90(m, 1, (1,2)) array([[[1., 3.], [0., 2.]],
- [[5., 7.],
[4., 6.]]])
