We ran into a subtle issue with the En-ROADS model and the latest SDE where sde would fail in the case where a subscripted variable is only partially defined in the mdl file. For example: Constant ...

All subscripted indices are converted into the 'Subcript' function in mathematica, which naturally supported multiple indices. While converting back from mathematica, the subscript function is ...

Abstract: The conventional axiomatic definitions are given for multiple assignment to simple variables and for assignment to a single subscripted variable, along with examples to illustrate their use.

You can pass expressions and subscripted matrices as arguments to a module, but you must be careful and understand the way IML evaluates the expressions and passes results to the module. Expressions ...

I have been trained to regard an array in the ALGOL 60 sense as a finite set of elementary, consecutively numbered variables, whose “identifiers” could be “computed”. But for two reasons this view ...
