Close the prompt to save simulink model using Matlab code

I am working on FOR loop, where simulink model will be run in a separate matlab window and closed using !taskkill \pid . In one of the simulink model file, I am getting a message prompt saying 'Save "Simulink Model" before closing' 1. Yes 2. No 3. Cancel.

I donot want to save the model. So, I had to click 2.No everytime.

1. Is it possible to select 2.No everytime?.
2. It is even better if you can suggest a way to avoid getting such a prompt, by changing some settings.

Hi Seshasai,

You could use the "/f" parameter with taskkill to forcefully terminate the process. Ofcourse, the changes made to that process will not be saved in this case. For example:

!taskkill /pid 13768 /f

If you want to run and close Simulink models in the same MATLAB instance, I suggest using the "bdclose" function which ignores the "Save" dialog box and reverts any changes before closing the model. Documentation link: bdclose

Thanks!! using /f has worked for me.
