1931	Do not scalarize vector equations	Martin Sjölund	Jens Frenkel	"We should not scalarize equations, so we can reduce the number of function calls performed (here f is called once for each element in the matrix):
{{{
model M
  function f
    input Real r1,r2;
    output Real o[2] := {r1,r2};
  end f;
  Real rtime = time;
  Real r[:,:](each start = 1.5) = f(rtime,2:3);
end M;

model N
  M m;
end N;
}}}

With a better frontend, we can generate this flat code:
{{{
function M.f
  input Real r1;
  input Real r2;
  output Real[2] o = {r1, r2};
end M.f;

class N
  Real m.rtime = time;
  Real m.r[1,1](start = 1.5);
  Real m.r[1,2](start = 1.5);
  Real m.r[2,1](start = 1.5);
  Real m.r[2,2](start = 1.5);
equation
  m.r = {M.f(m.rtime, 2.0), M.f(m.rtime, 3.0)};
end N;
