jax.numpy.swapaxes¶

jax.numpy.swapaxes(a, axis1, axis2)[source]¶

Interchange two axes of an array.

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

Parameters

a (array_like) – Input array.
axis1 (int) – First axis.
axis2 (int) – Second axis.

Returns

a_swapped – For NumPy >= 1.10.0, if a is an ndarray, then a view of a is returned; otherwise a new array is created. For earlier NumPy versions a view of a is returned only if the order of the axes is changed, otherwise the input array is returned.

Return type

ndarray

Examples

>>> x = np.array([[1,2,3]])
>>> np.swapaxes(x,0,1)
array([[1],
       [2],
       [3]])

>>> x = np.array([[[0,1],[2,3]],[[4,5],[6,7]]])
>>> x
array([[[0, 1],
        [2, 3]],
       [[4, 5],
        [6, 7]]])

>>> np.swapaxes(x,0,2)
array([[[0, 4],
        [2, 6]],
       [[1, 5],
        [3, 7]]])
