functionsmoothLimit
Once continuously differentiable approximation to the limit function
Extends from Modelica.Icons.Function.
Information
Once continuously differentiable approximation to the limit(.,.) function.
The output is bounded to be in [l, u].
Note that the limit need not be respected, such as illustrated in Buildings.Utilities.Math.Examples.SmoothMin.
