Save figure with all subplots

I generated a lot of figures with subplots. I want to save them and don't want to display them.

I realized only the last subplot is saved. Is there anyway I can save all subplots in a figure.

The following is an example code.

t=linspace(1,10,20);
y=2*t;

for i=1:3
    f=figure('visible','off');
    subplot(1,3,i)
    p=plot(t,y);
    saveas(f,'test','jpg')
end

how to save 1 figure of the subplots

Construct new file names each iteration.

saveas(f, sprintf('test%d.jpg', i))

Thank you Walter.

I made the mistake using

figure('visible','off')

So it generates new figure every loop.

After correcting it to

t=linspace(1,10,20);
y=2*t;

for i=1:3
    f=figure(1);
    set(f,'Visible', 'off')
    subplot(1,3,i)
    p=plot(t,y);
    saveas(f,'test','jpg')
end

It works.

That would overwrite test.jpg each iteration.

You are right. I should put saveas outside the loop.

I'd also like to point readers in the direction of exportgraphics instead of saveas.

exportgraphics(fig, filename)
