.Annex60.Utilities.Math.Functions.spliceFunction

Information

Function to provide a once continuously differentiable transition between to arguments.

The function is adapted from Modelica.Media.Air.MoistAir.Utilities.spliceFunction and provided here for easier accessability to model developers.

Interface

function spliceFunction
  input Real pos "Argument of x > 0";
  input Real neg "Argument of x < 0";
  input Real x "Independent value";
  input Real deltax "Half width of transition interval";
  output Real out "Smoothed value";
end spliceFunction;

• May 10, 2013, by Michael Wetter:
  Reformulated implementation to avoid unrequired computations.
• May 11, 2010, by Michael Wetter:
  Removed default value for transition interval as this is problem dependent.
• May 20, 2008, by Michael Wetter:
  First implementation.
