# jax.numpy.rot90ΒΆ

jax.numpy.rot90(m, k=1, axes=(0, 1))[source]ΒΆ

Rotate an array by 90 degrees in the plane specified by axes.

LAX-backend implementation of rot90(). Original docstring below.

Rotation direction is from the first towards the second axis.

Parameters
• m (array_like) β Array of two or more dimensions.

• k (integer) β Number of times the array is rotated by 90 degrees.

Returns

y β A rotated view of m.

Return type

ndarray

flip()

Reverse the order of elements in an array along the given axis.

fliplr()

Flip an array horizontally.

flipud()

Flip an array vertically.

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]])
>>> np.rot90(m)
array([[2, 4],
[1, 3]])
>>> np.rot90(m, 2)
array([[4, 3],
[2, 1]])
>>> m = np.arange(8).reshape((2,2,2))
>>> np.rot90(m, 1, (1,2))
array([[[1, 3],
[0, 2]],
[[5, 7],
[4, 6]]])
