ATANH Inverse Hyperbolic Tangent Function

Section: Mathematical Functions


Computes the inverse hyperbolic tangent of its argument. The general syntax for its use is
  y = atanh(x)

where x is an n-dimensional array of numerical type.

Function Internals

The atanh function is computed from the formula

where the log (and square root) is taken in its most general sense.


Here is a simple plot of the inverse hyperbolic tangent function
--> x = -0.99:.01:0.99;
--> plot(x,atanh(x)); grid('on');
