Code generation does not support multiple iterators

[Francesco Casella]

Multiple iterators are not supported in OMC. This can be tested by simulating the following simple model:

model foo
  parameter Integer nRows = 3,nCols = 3;
  Real hilb[nRows,nCols] = array(1/(i+j-1) for i in 1:nRows, j in 1:nCols);
end foo;

which gives the following error:

[CodegenC.tpl:8122:14-8122:14:writable] Error: Template error: Code generation does not support multiple iterators: array(DIVISION(1.0, /*Real*/(i + j + -1), #SHARED_LITERAL_0(String)#) for j in #SHARED_LITERAL_1(Integer[3])#, i in #SHARED_LITERAL_1(Integer[3])#)

But at least I added a nice message saying it's not working, right? ;)

Maybe we should rewrite multiple iterators to for loops as those are supported already as far as i know.

[Martin Sjölund]

Nah, you can rewrite them to 2 different iterators instead. Or fix them in the runtime (Ceval handles them).

Moved to new milestone 1.9.4

[Francesco Casella]

It seems that the problem has been solved in the meantime, as the reported test case works fine with omc v.1.9.4-dev-184-g7bf48ba
