## ACOSH Inverse Hyperbolic Cosine Function

Section: Mathematical Functions

### Usage

Computes the inverse hyperbolic cosine of its argument. The general syntax for its use isy = acosh(x)

where `x`

is an `n`

-dimensional array of numerical type.

### Function Internals

The`acosh`

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 cosine function--> x = linspace(1,pi); --> plot(x,acosh(x)); grid('on');
