Close all messageboxes (generated by Simulink)

I'd like to know how to close all messageboxes that Simulink occasionally creates (in my case these are unimportant warnings after machine initialization command in SimPowerSystems, but this could be something else). There were some answers on how to close a messagebox (e.g. like this one), but they all assume that the messagebox handle is known, which is something that people may have when they create messageboxes themselves. My messageboxes are, however, generated by Simulink.

Answer 1

[TAB]

If title of the message box is same each time they are generated, then you can search the existing open figures by their name and close them.

MsgBoxH = findall(0,'Type','figure','Name','TitleOfMsgBox');
close(MsgBoxH);
