## ATANH Inverse Hyperbolic Tangent Function

Section: Mathematical Functions

### Usage

Computes the inverse hyperbolic tangent of its argument. The general syntax for its use isy = 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');
