csch (MATLAB Functions)

Hyperbolic cosecant

Syntax

```
Y = csch(x)
```

Description

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

Y = csch(x) returns the hyperbolic cosecant for each element of x.

Examples

Graph the hyperbolic cosecant over the domains and .

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

Definition

The hyperbolic cosecant can be defined as
