ATANH Inverse Hyperbolic Tangent Function

Section: Mathematical Functions

Usage

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.

Examples

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