did anybody know how to find arctanh using cordic algorithm.
(using microrotations) .
i need to find out arctan and arctanh . arctan can be easily implemented using vector mode.

but arctanh i am not able to find !!!(i only wanted to know how to find arctanh using cordic methode).

You could use this identity:

tanh(z) = -i tan(iz)
