Question

I have a .m file where I do some actions with Simulink model, and I would like to check if the currently used model is the entire model or a subsystem. Is there a specific syntax or function to check this? I need to be able to perform actions differently depending on Simulink system.

You can always use bdroot to get the name of the top level system and use string comparison to see if you have a subsystem or not:

sysname = 'f14/Actuator Model';
istoplevel = strcmp(bdroot(sysname), sysname);
