Is there a possibility to store variant objects in a structure?

Dear community,

I need your help again. And it is still about variant subsystems. My model runs perfectly but unfortunately it is very big. Thats why I have a lot of variant objects in the base workspace after simulation. I tried something like that:

The variant Subsystem A needs the variant objects a1, a2 and a3. I generated a structure 'variant_objects' and stored the objects for A in this structure:

variant_objects.a1 = Simulink.Variant('true()');
variant_objects.a2 = Simulink.Variant('false()');
variant_objects.a3 = Simulink.Variant('false()');

The 'Variant choices' table of A looks good. The right subsystem seems active. But when I try to simulate the model I get an error message:

The variant 'variant_objects.a1' of the variant block 'test_Variant/Variant Subsystem' must be the name of a Simulink.Variant object in the base workspace.

Is there a possibility to bundle variant objects in the base workspace? I'm using Matlab 2010b SP1 and have no possibility to switch to another Matlab version.

Thanks for your help!

Bettina

Hi Bettina,

I'm just wondering if you ever found a solution to this. I am having exactly the same problem with the same version of Matlab you are using. It's frustrating that the parameter dialog box has no problem with the variant objects being in a structure but simulation engine can't deal with it properly.

Thanks,

Andy
