button unresponsive while running loop

I have a button that toggles the state of a rogue variable which will terminate a while loop. However, if the while loop is running, the button is unresponsive, and I cannot break the loop without using "ctrl + C".

Hi Rohit,

You can use 'drawnow' or one of its functional equivalents, such as 'pause(0)' inside of the while loop when it is running and button is unresponsive.

Adding this allows the system to register that the variable has updated, which subsequently breaks the loop.

Please refer the following documentation for drawnow function: https://www.mathworks.com/help/matlab/ref/drawnow.html
