/**

|
|
* Calculate the hyperbolic arccosecant of a value,
|
||
|
|
* defined as `acsch(x) = asinh(1/x) = ln(1/x + sqrt(1/x^2 + 1))`.
|
||
|
|
*
|
||
|
|
* For matrices, the function is evaluated element wise.
|
||
|
|
*
|
||
|
|
* Syntax:
|
||
|
|
*
|
||
|
|
* math.acsch(x)
|
||
|
|
*
|
||
|
|
* Examples:
|
||
|
|
*
|
||
|
|
* math.acsch(0.5) // returns 1.4436354751788103
