Say I have a nonvirtual bus named FooBus defined in the Simulink type editor. How would I get FooBus's Bus Object (so I can access its element definitions), given only its name as a string (ie "Bus: FooBus")?
Put another way, I'm looking to get the following object having only the name of the bus.
Bus with properties:
Description: ''
DataScope: 'Auto'
HeaderFile: ''
Alignment: -1
PreserveElementDimensions: 0
Elements: [4×1 Simulink.BusElement]

Hi Dominic,
You can use the 'evalin' function for this purpose. Assuming you have defined your bus object in the base workspace with the name 'FooBus', you can access the object through its name in the following manner:
bus_name = 'FooBus';
bus_obj = evalin('base',bus_name)
For more information on the use of this function, you can refer to: https://www.mathworks.com/help/matlab/ref/evalin.html
Hope this helps.
