# csch

Hyperbolic cosecant

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

collapse all

Plot the hyperbolic cosecant over the domain 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

## More About

### Hyperbolic Cosecant

The hyperbolic cosecant of z is

$\text{csch}\left(z\right)=\frac{1}{\mathrm{sinh}\left(z\right)}.$

### Tall Array Support

This function fully supports tall arrays. For more information, see Tall Arrays.
