<p>Hello,</p>
<p>I might be wrong but Atanh can be written in terms of log as
Atanh(x) = 1/2 ln((1+x) / (1-x)) ? If yes you can compute it in a
GetDP script ("ln" function is "Log" in GetDP).<br>

<p class="MsoNormal">Hello everyone, I would like to know if
there is any way to add the atanh [] function in getDP since I
am in need of it. Is there any way to add some function to a
solver? I'm trying to do the same as the
<a class="moz-txt-link-rfc2396E" href="http://onelab.info/wiki/C%2B%2B">"http://onelab.info/wiki/C%2B%2B"</a> example but I'm getting the
following error "Abnormal server termination (Socket listening
timeout on socket 127. ...) ". I need the Atanh function
because I am trying to solve the transcendent equation of a
metal metal dielectric metal waveguide.</p>
