In matlab code, create a generic element using
myElement = Simulink.BusElement;
You can set the properties of the new element by directly accessing the values. For example
myElement.Name = 'mySignal';
myElement.DataType = 'uint8';
Once you are finished with the element, you can add it to the bus:
myBus = Simulink.Bus;
myBus.Elements(end+1) = myElement;
Another way to create bus objects is to implement the bus in simulink with all its inputs with correct data types and sizes. For example like this:
Select the bus creator block and run the following code:
Simulink.Bus.createObject(gcs, gcb);
This will put a bus object named like the output signal of the bus creator, in this case myBus, in the workspace.
