Changing model programmatically: discard changes and exit?

Hi,

I programmatically change a model in Simulink, run the simulation, and exit.

open_system(...)
add_block(...)
sim(...)

When I run it again, I get an error from add_block() that the block already exists.

So I add

save_system('different_name') 

and than I can run the model again with no problem.

However, I would like to exit without saving the modified model.

Is it possible to somehow discard the changes and exit?

You can stop/quit via the cmd prompt:

!TASKKILL /F /IM MATLABWindow.exe /T &
