Display message in GUI when solver stops prematurely

I have a GUI that executes perfectly when the user enters the right information. However, if some datum doesn't coincide with the ones written before, the optimization algorithm (fmincon) can't find a proper answer. I have no problem with this, but I'd like to display a message (msgbox) when the "Solver stopped prematurely" but I can't find how to refer to this situation in the GUI.

Thank you for your assistance.

You can use the try-catch statement to handle potential errors and override default behavior. Documentation here .

Alright, then I'll try with those commands. Thank you
