MATLAB Function Reference

csch - 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

Algorithm

csch uses FDLIBM, which was developed at SunSoft, a Sun Microsystems, Inc. business, by Kwok C. Ng, and others. For information about FDLIBM, see http://www.netlib.org.
