saving figures in matlab

Hello.

I am generating bunch of figures in matlab which is in a for loop. I would like to save them both in .fig and .jpg. Right now I am first plotting the figure and then save them. But I don't really need to see the figures and I just want to save them. Is there anyway that I do this so that the speed increases?

Thanks

You can try using an invisible figure:

% create an invisible figure
f = figure('visible', 'off'); 
% loop 10 times, saving .fig and .jpeg for a random plt
for idx = 1:10
    % plot your data 
    plot(rand(10)); 
    % save as .fig 
    savefig(f, sprintf('figure%d.fig', idx)); 
    % save as jpeg
    print(f, '-djpeg', sprintf('figure%d.jpg', idx));
    % clear the figure 
    clf(f); 
end
delete(f);

Put

drawnow

right after you display the images. If it's still too fast, put in a

pause(0.3)

to delay it a little bit.

Don't save as .fig or .jpg. Save the axes as a .PNG. I recommend you use export_fig. http://blogs.mathworks.com/pick/2010/05/28/creating-and-exporting-publication-quality-graphics/
