Hi,

I am running a code where I plot images in a 2 for loops. I got 3 different buttons that allows me to go to the iteration "Next", analyse the image or go back to the previous image "previous" iteration. However, in this case I got a an issue. I am trying to go back an iteration(i.e. if n=3 and nn=2 or 3) I want to go one backwards on that for loop. However if nn=1. I need to go one back in the n for loop and the last of the nn. at the moment It does't do that. This is a part of the code, I could provide the whole of it if needed.

for n= 1:length(DigMark) aproxx(1:100)
    for nn=1:length(Mucles) aprox(1:3)
        message= sprintf('Select one of the following:');
        titleBarCaption = 'Manual';
        Button = questdlg(message, titleBarCaption, ...
            'Previous','Analyses','Next', 'Analyses');
        if strcmpi(Button, 'Previous') && nn == 1
            s=s-1 ;
            n = n - 1;
            nn= length(EMG);
            keyboard
            outputTable(end, :)=[];
            close(figu);
        elseif strcmpi(Button, 'Previous') && nn > 1
            s=s-1 ;
            nn= nn-1;
            keyboard
            outputTable(end, :)=[];
            close(figu);
            continue;
        end
    end
end
