MATLAB Function Reference

coth - Hyperbolic cotangent

Syntax

Y = coth(X)

Description

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

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

Examples

Graph the hyperbolic cotangent over the domains and

x1 = -pi+0.01:0.01:-0.01; 
x2 = 0.01:0.01:pi-0.01;
plot(x1,coth(x1),x2,coth(x2)), grid on

Definition

The hyperbolic cotangent can be defined as

Algorithm
