Hold on with subplot in a loop

Hello,

Hold on, command is messing up my life. I was trying to plot figures using a loop. I want the first two loops in one subplot and the next two loops in another subplot. I tried to hold off and it didn't work.

A={[40;50;60] [70;80;90] [20;30;50]};
B={[45;55;65] [75;85;95] [25;35;55]};
T=[1;2;3];
for i=1:length(A)
    figure(i)
    subplot(2,1,1)
    plot(T,A{i},'-r')
    hold on
    plot(T,B{i},'--b')
    xlabel('x')
    ylabel('y')
end
for i=1:length(A)
    figure(i)
    subplot(2,1,2)
    plot(T,cumtrapz(A{i}),'-r')
    hold on
    plot(T,cumtrapz(B{i}),'--b')
    xlabel('xdot')
    ylabel('ydot')

end
hold off
for i=1:length(A)
    figure(i)
    subplot(2,1,1)
    loglog(T,A{i},'-y')
    hold on
    loglog(T,B{i},'--g')
    xlabel('ftx')
    ylabel('fty')
end
for i=1:length(A)
    figure(i)
    subplot(2,1,2)
    loglog(T,cumtrapz(A{i}),'-y')
    hold on
    loglog(T,cumtrapz(B{i}),'--g')
    xlabel('ftxdot')
    ylabel('ftydot')
end

A={[40;50;60] [70;80;90] [20;30;50]};
B={[45;55;65] [75;85;95] [25;35;55]};
 
T=[1;2;3];
 figure(1)  % use this outside of loop
for i=1:length(A)
   
    subplot(2,1,1)
    plot(T,A{i},'-r')
    title('figure 1')
    hold on
    plot(T,B{i},'--b')
    xlabel('x')
    ylabel('y')
end
for i=1:length(A)
     
    subplot(2,1,2)
    plot(T,cumtrapz(A{i}),'-r')
    hold on
    plot(T,cumtrapz(B{i}),'--b')
    xlabel('xdot')
    ylabel('ydot')

end
hold off

figure(2) % same here too
for i=1:length(A)
    
    subplot(2,1,1)
    loglog(T,A{i},'-y')
    title('figure ')
    hold on
    loglog(T,B{i},'--g')
    xlabel('ftx')
    ylabel('fty')
    grid on
end
for i=1:length(A)
    
    subplot(2,1,2)
    loglog(T,cumtrapz(A{i}),'-y')
    hold on
    loglog(T,cumtrapz(B{i}),'--g')
    xlabel('ftxdot')
    ylabel('ftydot')
    grid on
end

Use figure outside of loop. you're trying to replicate figure windows with as many as size of your matrix A,

[Teshome Kumsa]

Your program is good, but it will not help me if my length (A) is too long. Of course, the reason why I want to replicate figures with as many as the size of my matrix is due to the large amount of data I have to work with. The code I put here is just a sample. It is not my real data. Assume my length (A) is 20. Does it make sense to plot 20 data sets in a single plot?
