## ACOTH Inverse Hyperbolic Cotangent Function

Section: Mathematical Functions

### Usage

Computes the inverse hyperbolic cotangent of its argument. The general syntax for its use is

      y = acoth(x)

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

### Function Internals

The `acoth` function is computed from the formula

### Examples

Here is a simple plot of the inverse hyperbolic cotangent function

    --> x = linspace(1,pi);
    --> plot(x,acoth(x)); grid('on');
