::

    `atanh`_




Particular cases
~~~~~~~~~~~~~~~~

In y=atanh(x), for real elements of x outside the domain [-1,1], the
complex part of Scilab y value is the opposite of Matlab y value.



Examples
~~~~~~~~
**Matlab** **Scilab**

::

    y = `atanh`_(2)
    y = 0.5493 + 1.5708i



::

    y = `atanh`_(2)
    y = 0.5493061 - 1.5707963i
