How can i stop the loop iteration using pushbutton callback in MATLAB GUI?

4 views (last 30 days)
I have GUI which has pushbutton to stop the for loop iteration. the code structure for stop button callback is follows
g = 1
handles.g = g
guidata(hObject,handles)
When i press the button, it sets the value of g = 1;
In the iteration loop, i have passed the updated value of g using
g = handles.g
and issuing a condition to stop the loop iterations
if g == 1
return
end
however, the iteration loop does not stop, since the value of g resets to 0
why does this happen ?

I have a very small demo that does exactly that. It start counting, then when you press stop, it stops counting and updating the text label on the GUI. Then when you press Go, it starts counting and updating the label again.

If you want to stop your iteration (for/while loop), you could try break instead of return.

yes, i have tried that as well. still it does not stop. because it does not enter the if loop, since the value of g resets to 0. why does this happen ?
