Information

Evaluate Bspline at one parameter safely, i.e. points outside the domain of the spline are moved inside the domain.

Interface

function safeEvaluateDer
  extends Modelica.Icons.Function;
  input Data spline "Bspline to be evaluated";
  input Real u "Parameter value at which Bspline shall be evaluated";
  output Real x[spline.ndim] "Value of Bspline at u";
  output Real xd[spline.ndim] "First derivative of Bspline at u";
end safeEvaluateDer;
