Reduction expression (from MathCore)

[Jan Brugård]

Reduction expression doesn't work. See for example the model:

model test
  Real A;
  parameter Real x[:]={1,2,3,4,5};
equation 
  A=min(x[j] for j in 1:size(x, 1));
end test;

The error messages from this model is:

--- [55] 12:51:27 Validation of class test ---
Check of test failed
Error: Type mismatch in equation A=<reduction>min(x[1] for j in {1,2,3,4,5}) of type Real=Real[5]
Error: Error occured while flattening model test

See the Modelica Spec 3.1 section 10.3.4 for more information about the reduction expressions.

Reduction are now implemented and working, except for reduction expressions where the range is an empty vector.
