Computes the inverse hyperbolic secant of x.

If x is not complex and is less than 0 or greater than 1, the result is NaN. The connector pane displays the default data types for this polymorphic function.

Example

	x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
	argsech(x) is of the same numeric representation as x.

Example

Refer to the Sine VI in the labview\examples\general\functions\Mathematics\Elementary & Special Functions\Trigonometric Functions directory for an example of using the Inverse Hyperbolic Secant function.
