My name is Oséias, I'm from Brazil and I study at University of São Paulo.
I'm using an evaluate version of Rhapsody, integrating it with simulink models.
I have one question abou it.

I have in my model 3 classes:
Generate
Simulation (it has a simulink stereotype)
Printing

Generate generates data for Simulation. When compiled, the prompt asks
values for each variable;
Simulation has the simulink block and it's C++ code from Real Time Workshop.
Printing prints the result of the simulation

I inserted the simulink block and code, I created the flow ports
following the rules for it and I could generate single values for each
port of simulink model.

But I want the generate matrices and vectors. How can I do it? Do I
need to declare an array? When I do it, I can't use the flowports.

I can declare variables in Generate as Real_T type from the Simulink
profile, but it just accepts single values. I'm asking if in Rhapsody
7.2 I can declare the variables as vector, as it's in Matlab.

Thanks

You can declare vectors and matrices in Simulink and those should be brought into Rhapsody as array types automatically. You should still be able to use these through flowports.
You may want to talk directly with technical support on this issue as they may be able to provide more assistance.
