function call, first argument is an array

[thorade]

See this Lightshow example:

or just the code below:

within ;
model SurfaceToAir "cool model"
  Modelica.Electrical.Analog.Basic.Resistor inRes[3,3];
  Modelica.Electrical.Analog.Basic.Resistor outRes[3,3];

equation 
  for j in 1:3 loop
    for k in 1:3 loop
      if inRes[j,k].R > 0 then
        outRes[j,k].R = Modelica.Math.cos(inRes[j,k].R - inRes[k,j].R);
      elseif inRes[j, k].R > 2 then
        outRes[j,k].R = Modelica.Math.cos( inRes[j,k].R - inRes[k,j].R);
      elseif inRes[j, k].R > 3 then
        outRes[j,k].R = Modelica.Math.sin(inRes[j, k].R - inRes[k,j].R);
      else
        outRes[j,k].R = 0;
      end if;
    end for;
  end for;
  annotation (uses(Modelica(version="3.2.1")));
end SurfaceToAir;
