i have a loop which runs from 1 to 7 producing four different figures per run. How do i automatically save each of these figures inside the loop. The loop is given below.

for n = 1:7
elevation = A_SATPOS(n).ELEV*(180/pi);
for PRN = 8
figure(); %first figure
subplot(2,1,1)

ylabel('Multipath [cm]')
ylim([-35 35]);

One thing I regularly do is something like this:
fig_basename = 'My_current_fig';
for i1 = 1:7
%plot-and-decorate-code
figname = sprintf('%s-%03d.eps',fig_basename,i1);
disp(['Now printing: ',figname])
print('-depsc2','-painters',figname)
end
You can adapt as you see fit. Occasionally I also keep a version-number that ticks up everytime I rund the script, to keep all sort of outputs for each run. For example:
% first in script:
load run_id.mat run_id
run_id = run_id+1;
save('run_id.mat','run_id')
% script-work...
% then at time of saving and printing
savename = sprintf('results-run-%d.mat',run_id)
fig_basename = sprintf('My_current_fig-run-%d',run_id);
That sometimes is handy.

Thanks for the suggestion. The figures are now being save. i used the first set of codes b ut i am unable to view them because they are not saved in jpeg or png format. Any suggestions ?
