Hyperbolic cotangent

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
