when to use bdclose versus close_system

Question

is there a difference between bdclose('sys') and close_system('sys', 0)?

i'm wondering if there are any memory cleanup differences or other reason to choose one or the other to close a model.

close_system cannot close system(or a simulink model) if it has unsaved changes. However, bdclose closes system unconditionally.

So, let's say you want to close a system which has unsaved changes, then you have to use save_system before going for close_system.

But, if you don't want to save the changes done in model, use bdclose.

that's why I specified close_system('sys', 0 ) setting the save flag to 0 allows close_system to close an unsaved system without saving it.
