numpy.transpose — NumPy v1.11 Manual (original) (raw)
numpy.transpose(a, axes=None)[source]¶
Permute the dimensions of an array.
| Parameters: | a : array_like Input array. axes : list of ints, optional By default, reverse the dimensions, otherwise permute the axes according to the values given. |
|---|---|
| Returns: | p : ndarray a with its axes permuted. A view is returned whenever possible. |
Notes
Use transpose(a, argsort(axes)) to invert the transposition of tensors when using the axes keyword argument.
Transposing a 1-D array returns an unchanged view of the original array.
Examples
x = np.arange(4).reshape((2,2)) x array([[0, 1], [2, 3]])
np.transpose(x) array([[0, 2], [1, 3]])
x = np.ones((1, 2, 3)) np.transpose(x, (1, 0, 2)).shape (2, 1, 3)
