|
* Calculate the hyperbolic arcsine of a value,

|
* defined as `asinh(x) = ln(x + sqrt(x^2 + 1))`.
|
||
|
|
*
|

|
* For matrices, the function is evaluated element wise.
|

|
|

* Syntax:

|
|
*
|
||
|
|
* math.asinh(x)
|

|

|
|
* Examples:
|
||
|
|
*
|
||
|
|
* math.asinh(0.5) // returns 0.48121182505960347
