示例1: arctanh

# 需要導入模塊: from numpy.core import numeric [as 別名]
# 或者: from numpy.core.numeric import arctanh [as 別名]
def arctanh(x):
    """
    Compute the inverse hyperbolic tangent of `x`.

    Return the "principal value" (for a description of this, see
    `numpy.arctanh`) of `arctanh(x)`. For real `x` such that
    `abs(x) < 1`, this is a real number.  If `abs(x) > 1`, or if `x` is
    complex, the result is complex. Finally, `x = 1` returns``inf`` and
    `x=-1` returns ``-inf``.

    Parameters
    ----------
    x : array_like
       The value(s) whose arctanh is (are) required.

    Returns
    -------
    out : ndarray or scalar
       The inverse hyperbolic tangent(s) of the `x` value(s). If `x` was
       a scalar so is `out`, otherwise an array is returned.


    See Also
    --------
    numpy.arctanh

    Notes
    -----
    For an arctanh() that returns ``NAN`` when real `x` is not in the
    interval ``(-1,1)``, use `numpy.arctanh` (this latter, however, does
    return +/-inf for `x = +/-1`).

    Examples
    --------
    >>> np.set_printoptions(precision=4)

    >>> np.emath.arctanh(np.eye(2))
    array([[ Inf,   0.],
           [  0.,  Inf]])
    >>> np.emath.arctanh([1j])
    array([ 0.+0.7854j])

    """
    x = _fix_real_abs_gt_1(x)
    return nx.arctanh(x)
