How to interrupt the optimisation routine (from Optimisation Toolbox)

Hello,

I wanted to create a GUI button that would exit the optimisation routine by setting STOP parameter of the output function to 1. However, whatever I do during the optimisation (after running ex. fmincon function), it will have effect only after the solver finishes. Can I somehow make an interruption that would execute while Matlab is 'busy' with optimisation? Is there any way of stopping the optimisation externally, apart from ctrl+c ?

I've seen some ideas with using try-catch procedure, but I'd rather avoid this to not change and complicate my code that much at a current level...

All plot functions have this as built-in functionality. Perhaps the simplest thing to do is to write a custom plot function, which will automatically create a GUI button to stop an optimization.
