nlcpy.transpose

nlcpy.transpose(a, axes=None)

Permutes the dimensions of an array.

Parameters

aarray_like

Input array.

axeslist of ints, optional

By default, reverse the dimensions, otherwise permute the axes according to the values given.

Returns

pndarray

a with its axes permuted. A view is returned whenever possible.

参考

moveaxis

Moves axes of an array to new positions.

argsort

Returns the indices that would sort an array.

注釈

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

>>> import nlcpy as vp
>>> x = vp.arange(4).reshape((2,2))
>>> x
array([[0, 1],
       [2, 3]])
>>> vp.transpose(x)
array([[0, 2],
       [1, 3]])
>>> x = vp.ones((1, 2, 3))
>>> vp.transpose(x, (1, 0, 2)).shape
(2, 1, 3)
