I want to run a model for different input parameters, using an arraySimulink.SimulaitonInput Objects.
In the StopFcn of the Model I want to read some of the model parameters and variables set by the simulink.SimulationInput objects.
To access the parameters I can call
get_param(gcs,'Parameter')
to get the value of the parameter as set by the Simulink.SimulationInput object.
However to access variables of the model I would need to do:
mdlWks = get_param(gcs,'ModelWorkspace');
Variable = getVariable(mdlWks,'Variable');
This however only gives me the default version of the value for Variable. I waat the current set value of Variable though. Is there an alternative get_var function or something that can do this?

Instead of using the StopFcn, maybe you can use setPostSimFcn functionality

Well, you could just as easily do that. But the original qeustion started with using using the StopFcn, so I thought you wanted to use automatic callback functionality. Either way, sounds like you have a path forward.

I just realized that the code I posted will overwrite output data in output of sim. The corrections would be pass the sim output into the post sim function, modify it, and return it.
simIn(ii) = setPostSimFcn(simIn(ii),@(simout) simpostfunc(out,simIn(ii).Variables));
function out = simpostfunc(out,simvariables)
% simple function to echo the simIn variables to the the simulation output
out.simvars = simvariables;
end
