acscd

computes the element-wise inverse cosecant of the argument, results in degree.

Calling Sequence

y = acscd(x)

Arguments

x

a real array.

y

a real or complex array.

Description

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

Sample

Examples

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