acsch

Inverse hyperbolic cosecant

Syntax

Y = acsch(X)

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.

Graph of Inverse Hyperbolic Cosecant Function

Graph the inverse hyperbolic cosecant function over the domains $-20 \le x \le -1$ and $1 \le x \le 20$.

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