# acoth

Inverse hyperbolic cotangent

Y = acoth(X)

## Description

Y = acoth(X) returns the inverse hyperbolic cotangent for each element of X.

The acoth function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

## Examples

expand all

### Graph of Inverse Hyperbolic Cotangent Function

Graph the inverse hyperbolic cotangent function over the domains and .

```x1 = -30:0.1:-1.1;
x2 = 1.1:0.1:30;
plot(x1,acoth(x1),x2,acoth(x2)), grid on
