My program produces small figures during the command cycle. Is there a way to just save these figures and then combine them in one figure later?
Amro's solution works greatly, but with boxplots you have to reset the Xtick and Xtick labels, otherwise, for some reason, they will not be resized according to the the subplot. When you create the boxplot or after opening the figure add:
set(gca,'XTick',<1d vector>,'XTickLabel',<1d cell vector>)
or put automatic ticks and labels
set(gca,'XTickMode','auto','XTickLabelMode','auto')
