ACSCH Inverse Hyperbolic Cosecant Function

Section: Mathematical Functions

Usage

Computes the inverse hyperbolic cosecant of its argument. The general syntax for its use is 
  y = acsch(x)

where x is an n-dimensional array of numerical type.

Function Internals

The acsch function is computed from the formula

Examples

Here is a simple plot of the inverse hyperbolic cosecant function 
--> x1 = -20:.01:-1;
--> x2 = 1:.01:20;
--> plot(x1,acsch(x1),x2,acsch(x2)); grid('on');
