acsc

computes the element-wise inverse cosecant of the argument.

Syntax

y = acsc(x)

Arguments

x

a real or complex array.

y

a real or complex array.

Description

Computes the element-wise inverse cosecant of the argument. For real argument with absolute value greater than 1 the result is real.

The following equalities hold: acsc(z) == -acsc(-z) == asin(1/z) == %pi/2-asec(z) == %i*acsch(%i*z)

Sample

Examples

x=linspace(1,20,200);
x=[-x($:-1:1) %nan x];
plot(x,acsc(x))
