Hello!

I wrote a simple GUI for testing but I cannot save my variable. This function is used in another script. What I need to do is to save variables val1, val2, val3 and val4 as a vector (loudness = [val1, val2, val3, val4]. I tried many many things but it cannot create the vector as these values are not known when the script is run. The code is available below. I would appreciate your help!

function mytemps
f = figure;
c = uicontrol(f,'Style','popupmenu');
c.Position = [20 150 90 50];
c.String = {'0','1','2', '3', '4', '5', '6', '7', '8', '9', '10'};
c.Callback = @selection1;
d = uicontrol(f,'Style','popupmenu');
d.Position = [160 150 90 50];
d.String = {'0','1','2', '3', '4', '5', '6', '7', '8', '9', '10'};
d.Callback = @selection2;
e = uicontrol(f,'Style','popupmenu');
e.Position = [300 150 90 50];
e.String = {'0','1','2', '3', '4', '5', '6', '7', '8', '9', '10'};
e.Callback = @selection3;
g = uicontrol(f,'Style','popupmenu');
g.Position = [440 150 90 50];
g.String = {'0','1','2', '3', '4', '5', '6', '7', '8', '9', '10'};
g.Callback = @selection4;
    function selection1(src,event)
      
        val1 = c.Value;
        str = c.String;
        val1 = str{val1};
        disp(['Loudness noise 1: ' val1]);     
 
    end
    function selection2(src,event)
        val2 = d.Value;
        str = d.String;
        val2 = str{val2};
        disp(['Loudness noise 2: ' val2]);
        
    end
    function selection3(src,event)
        val3 = e.Value;
        str = e.String;
        val3 = str{val3};
        disp(['Loudness noise 3: ' val3]);
        
    end
    function selection4(src,event)
        val4 = g.Value;
        str = g.String;
        val4 = str{val4};
        disp(['Loudness noise 4: ' val4]);
    end
end
