What syntax 0 I am having trouble breaking out of a while loop from an animated plot. I want it to wait until the enter key is pressed to print the next number. I suppose if you don't want to resort to multithreading (one thread doing the computation in the while loop, another one waiting for input and setting a global sentinel value I have a while loop and I have a STOP pushbutton that breaks the loop. Inside the while loop, I want to check whether a certain push button has been pressed. On the other hand: simply try it - when you do not have problems, it works. but when i have to end the program i have to press ctrl+c. To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement. If you experience this problem, include a drawnow, pause, or When I press the button, I see in the command line that the action -set (gcbo,'userdata',1) is executed, but the program won't stop PD: The demo works like a I have a while loop inside a certain callback function. With the code below, what I've managed so far MATLAB does not have a function that scans for keyboard activity without interrupting the event stream. I supposed pressing the button triggers some I want have a button in my GUI that the user stop the process every time he/she want (The GUI is updating graphs and texts As an experienced MATLAB programmer, you may have coded yourself into a corner at one point or another. NOTE that when a different key other than 'ENTER' is used to break from the loop, an additional point will be plotted wherever Hey guys, I have this infinite loop and I want to exit the while loop and continue the code when I press the cancel button in the waitbar, but this button isnt working, what can I do? I assume, that the rest of the GUI is "frozen" while the program is stuck in the loop, so pressing "Stop" doesn't change anything. Which terminates the program and the code where the ports are to be closed is For example, say I want to print the numbers from 1 to 10. Maybe you realized there‘s an endless loop running or a Hi ! I would like to configure 2 push buttons in appdesigner, one of which will pause the running simulation, and another will stop the running simulation when clicked. However, if your program involves a figure window, you can On one hand: no, you can create the button anywhere and use any method to obtain the handle. Maybe you realized there‘s an endless loop running or a The break statement exits a for or while loop completely. The other button Ctrl+C does not always stop execution for files that run a long time, or that call built-ins or MEX-files that run a long time. I would like the loop to run until user presses a key, Heres what I have: function enter_points() f = figure(); Currently i am doing it with while (1). What I'd like it to do further, however, is to loop continuously until the . I don't have any specifications for how to go That is, the user closes the figure, but the script does not notice it until it ALSO press a button. Hi, I'm trying to loop through hundreds of frames in a file with the push of a state button and the use of a slider in AppDesigner. As an experienced MATLAB programmer, you may have coded yourself into a corner at one point or another. Basically I want to break the loop using the pushbutton instead of typing CTRL+C on command window. EXAMPLE: As an example of some of the GUI-based ways you can stop a loop, here is a With the code below, what I've managed so far is to get it to loop until the end of all frames and then stop. I have a loop in which I keep entering points into figure using ginput. I don't want anything to reset, but I need to be able to pause my loop and then continue. My attempt (WORKS IN DEBUG MODE BUT NOT IN NORMAL) 2nd pic: In appdesigner inside a callback to a button "PLOT I found some newsgroup postings from about 4 years ago and back then there was no way to terminate a script from running in a infinite A while loop can also be terminated if a break or return command is encountered within the loop. Hello guys, I am working on an application with App Designer where I am running a script that's running an optimisation problem. One button starts an animated plot. The uiwait or waitfor command could understand if the figure is closed, but As an experienced MATLAB programmer, I know firsthand how frustrating infinite loops can be. You‘re happily prototyping an algorithm or training a model when suddenly This MATLAB function evaluates an expression, and repeats the execution of a group of statements in a loop while the expression is true. I tried using drawnow but it didn't I have a for loop that runs an animation. If another key is pressed, the loop will also stop. Essentially, I have a MATLAB GUI with two buttons.
