Hi,

I have a GUI written in appdesigner with a function that takes a data matrix and uses it to display a "frame", running this in a while loop results in a video being played. This is the code for it:

        function PlayButtonPushed(app, event)
            % Start conditions
            Frame              = app.CurrentFrame.Value;
            PauseTime               = app.TimeBetweenFrames.Value;
            NumOfFrames(1)             = app.Arena(1).File.NumberOfFrames;
            % Main loop
            while Frame <= NumOfFrames
                
                DisplayFrame(app, Frame);
                drawnow % Update GUI after displaying frame
                pause(PauseTime);
                
                % Stop condition
                if strcmp(app.StopValue, 'On')
                    app.StopValue='Off';
                    break
                end
                
                % Update conditions for the next frame
                FrameInterval = app.FrameInterval.Value;
                Frame         = app.CurrentFrame.Value+FrameInterval;
                app.CurrentFrame.Value = Frame;
                PauseTime     = app.TimeBetweenFrames.Value;
                app.TimeBetweenFrames.Value = PauseTime;
            end
            end

So as you can see, app.Arenas is an array and currently it only display the first arena, I would like to expand on it, being able to view two or four(or n, for a generallity) arenas at the same time. I could just loop the "DisplayFrame" function for n but I may want to take in to account the fact that maybe different arenas have a different "total frames" for them, and also, looping it will be a lot slower.

Is there anyway to have this function run multiple times, simultaneously?

Thanks!
