How can I create a bus for Simulink from a Matlab function?

I have a function (myFunc) where I call a Simulink model that uses bus structures.

Before calling the model from myFunc, I used the following commands to create the bus and just run the model:

              % References
                  busInfo2=Simulink.Bus.createObject(REF);
                  RefVectorBus = eval(busInfo2.busName);        
                  clear slBus1; %(slBus1 is the default name. As I changed it to RefVectorBus, I can clear  slBus1)           
              % Controller Configuration
                  busInfo3=Simulink.Bus.createObject(controllerConfig);
                  controllerConfigBus = eval(busInfo3.busName);
                  clear slBus1;

But now that I have this:

output = myFunc (input)
   //declare model parameters (as I use current workspace)
   //initialize bus:
              % References
                  busInfo2=Simulink.Bus.createObject(REF);
                  RefVectorBus = eval(busInfo2.busName);        
                  clear slBus1;      
              % Controller Configuration
                  busInfo3=Simulink.Bus.createObject(controllerConfig);
                  controllerConfigBus = eval(busInfo3.busName);
                  clear slBus1;
   //call the model (USING CURRENT WORKSPACE)
        SimulationOut = sim('myModel','SaveOutput','on', 'SrcWorkspace','current');
   ...
end (myFunc)

The problem is that Matlab doesn't allow me to create the bus ("Undefined function or variable 'slBus1'"). Is there a problem with the current workspace? Is matlab looking for the bus info in the base workspace?

I need the current workspace because the myFunc is a fitness function handle for a genetic algorithm and some of the Model parameters are beig estimated so I have to define them INSIDE myFunc and not in the base Workspace.

How can I solve this? Thanks to you

When using `Simulink.Bus.createObject` Matlab assigns the bus object to the base workspace and, as far as I know, this behavior can't be changed.

If you want to recover the Simulink bus in the current workspace use `evalin`

busInfo=Simulink.Bus.createObject(struct);
slBus = evalin('base',busInfo.busName);

See the evalin docs.
