Inverse hyperbolic tangent
atanh function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Y = atanh(X)
returns the inverse hyperbolic tangent for each element of
Graph the inverse hyperbolic tangent function over the domain .
The hyperbolic inverse tangent can be defined as
