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

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)
