Hi,

I have a nested for loop in App Designer, which I am using to change two parameters (AOIc and Lgc) and to plot a graph after each loop. After each nested loop I am calculating the minimum width of the graphs. I want to hold on to the graphs with minimum widths and to hold off all the others. By other words, at the very end I want to have only the graphs with minimum width.

Please see the portion of my code that is trying to do this. In its current state, it plots the one with minumum width after the first loop and loses the ones that are not necessary (that's good!), but after the second loop it also loses the first minimum.

% initial conditions
AOIc = app.AOIc.Value; % deg
AOIc_step = app.AOIc_step.Value; % deg
AOIc_number = app.AOIc_number.Value;
AOIc0 = AOIc - AOIc_step*AOIc_number/2;
AOIcstart = app.AOIc.Value; % deg
Lgc = app.Lgc.Value; % cm
Lgc_step = app.Lgc_step.Value; % cm
Lgc_number = app.Lgc_number.Value;
Lgc0 = Lgc - Lgc_step*Lgc_number/2;
Lgcstart = app.Lgc.Value; % deg
            
tlim = app.tlim.Value;
tstep = app.tstep.Value;
t = -tlim:tstep:tlim; % time (fs)
            
durt = NaN(AOIc_number+1,Lgc_number+1); % array of temporal duration (or width) values to be filled after each loop
            for k = 1:AOIc_number+1
                AOIc(k) = AOIc0 + (k-1)*AOIc_step;
                app.AOIc.Value = AOIc(k);
                app.AOIc_number.Value = k;
                drawnow()
                for kk = 1:Lgc_number+1
                    Lgc(kk) = Lgc0 + (kk-1)*Lgc_step;
                    app.Lgc.Value = Lgc(kk);
                    app.Lgc_number.Value = kk;
                    drawnow()
                    CalculatepButtonPushed(app, event) % calculates and plots pulse on UIAxes1 using "CalculatepButtonPushed" function above
                    drawnow()
                    I = app.I2; % property
                    Iarray(kk,:) = I;
                    app.dur.Value = width(I)*tstep;
                    durt(k,kk) = app.dur.Value;
                end
                [min_durt0,y0] = min(durt(k,:));
                hold(app.UIAxes1, 'off')
                plot(app.UIAxes1,t,Iarray(y0,:),'w','LineWidth',2)
                hold(app.UIAxes1, 'on')
                pause(1)
            end
