acsch - Inverse hyperbolic cosecant

Syntax

Description

Y = acsch(X) returns the inverse hyperbolic cosecant for each element of X.

The acsch 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 cosecant over the domains –20 ≤ x ≤ –1 and 1 ≤ x ≤ 20.

x1 = -20:0.01:-1; 
x2 = 1:0.01:20; 
plot(x1,acsch(x1),x2,acsch(x2)), grid on

Definitions

The hyperbolic inverse cosecant can be defined as

Algorithms
