numpy.swapaxes — NumPy v1.11 Manual (original) (raw)
numpy.swapaxes(a, axis1, axis2)[source]¶
Interchange two axes of an array.
| Parameters: | a : array_like Input array. axis1 : int First axis. axis2 : int Second axis. |
|---|---|
| Returns: | a_swapped : ndarray For Numpy >= 1.10, 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. |
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]]])
