Matlab/Scilab equivalent
~~~~~~~~~~~~~~~~~~~~~~~~
**Matlab** **Scilab**

::

    `acoth`_(A)



::

    `atanh`_((1) ./A)




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

In Matlab **y=acoth(x)** and Scilab **y=atanh(1 ./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. See
**atanh**.
