ArcTanh

ArcTanh(
       x             ! (input) numerical expression
       )

Arguments

x

A scalar numerical expression in the range \((-1,1)\).

Return Value

The ArcTanh function returns the inverse hyperbolic tangent of x.

Note

  • A run-time error results if x is outside the range \((-1,1)\).

  • The function ArcTanh can be used in constraints of nonlinear mathematical programs.
