Méthode numpy.matlib.ndarray.transpose

Signature de la méthode transpose

Description

help(ndarray.transpose)

a.transpose(*axes)

    Returns a view of the array with axes transposed.

    Refer to `numpy.transpose` for full documentation.

    Parameters
    ----------
    axes : None, tuple of ints, or `n` ints

     * None or no argument: reverses the order of the axes.

     * tuple of ints: `i` in the `j`-th place in the tuple means that the
       array's `i`-th axis becomes the transposed array's `j`-th axis.

     * `n` ints: same as an n-tuple of the same ints (this form is
       intended simply as a "convenience" alternative to the tuple form).

    Returns
    -------
    p : ndarray
        View of the array with its axes suitably permuted.

    See Also
    --------
    transpose : Equivalent function.
    ndarray.T : Array property returning the array transposed.
    ndarray.reshape : Give a new shape to an array without changing its data.

    Examples
    --------
    >>> import numpy as np
    >>> a = np.array([[1, 2], [3, 4]])
    >>> a
    array([[1, 2],
           [3, 4]])
    >>> a.transpose()
    array([[1, 3],
           [2, 4]])
    >>> a.transpose((1, 0))
    array([[1, 3],
           [2, 4]])
    >>> a.transpose(1, 0)
    array([[1, 3],
           [2, 4]])

    >>> a = np.array([1, 2, 3, 4])
    >>> a
    array([1, 2, 3, 4])
    >>> a.transpose()
    array([1, 2, 3, 4])
