acoth - Inverse hyperbolic cotangent

Syntax

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

Graph the inverse hyperbolic cotangent over the domains –30 ≤ x < –1 and 1 < x ≤ 30.

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

Definitions

The hyperbolic inverse cotangent can be defined as
