symmetric code generation error

[mathias.duwe@…]

following model results in error message given below.

model symTest
  parameter Integer n =3;
  Real A[:,:] = symmetric(2*identity(n)-[[0,time,0];[0,0,time];zeros(1,n)]);
end symTest;

I have fixed the simplification of the symmetric call in the frontend now, so that the given model works. symmetric is still not implemented in the simulation runtime though, so the real issue remains. There's also a couple of other issues, such as zeros not working with variable inputs.

I've got more important things to fix at the moment though, so the remaining issues will be fixed when I have time or someone yells at me loud enough.
