[App Designer]how to make endless loop program.
显示 更早的评论
I want to create an app that continuously receives input and displays new images.
If I simply put a function that creates an image like below,
while(flag)
function make_image()
end
the program seems to freeze. How should I design it?

Make sure there's a drawnow() being called somewhere within the loop.
while(flag)
make_image();
drawnow();
end

@Jae-Hee Park - why is a while loop needed? When the new data is received, draw the image then. The problem with the while loop is that your code will become "stuck" within it and no other action (GUI button press, callback, etc.) will be called unless you make the loop interruptible by introducing a pause or the drawnow like @Benjamin suggests.

@Jae-Hee Park - consider using a timer to periodically update your image. The timer could have a period of one second (or less) and within its callback, you would make the update (similar to the body of your while loop).
