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)

plot(elevation(first_half,PRN,1),MP1(first_half,PRN),'-','LineWidth',1)

ylabel('Multipath [cm]')

ylim([-35 35]);

xlabel('Elevation [degrees]')

%xlabel((sprintf('Time [hours] %s', days{day})))

title (sprintf('GPS L1 [HEL2] 00:00 - 11:59, G%s, %s', satNo{PRN}, days{n}));

%legend('Multipath','Elevation angle')

set(gca,'XLim',[0 90])

set(gca,'XTick',(0:10:90))

grid minor

subplot(2,1,2)

plot(elevation(second_half,PRN,1),MP1(second_half,PRN),'-','LineWidth',1)

ylabel('Multipath [cm]')

ylim([-35 35]);

xlabel('Elevation [degrees]')

%xlabel((sprintf('Time [hours] %s', days{day})))

title (sprintf('GPS L1 [HEL2] 12:00 - 23:59, G%s, %s', satNo{PRN}, days{n}));

%legend('Multipath','Elevation angle')

set(gca,'XLim',[0 90])

set(gca,'XTick',(0:10:90))

grid minor

for ob_type = 1

cno = A_OBS(n).CN0;

figure() %second figure

yyaxis left

plot(new_time, cno(:,PRN,ob_type),'-','LineWidth',1)

ylabel(sprintf('%s, CNO [dB-Hz]', cn0type{ob_type}))

ylim([0 60]);

set(gca,'YTick',(0:5:60))

yyaxis right

plot(new_time, MP1(:,PRN),'-','LineWidth',1)

ylim([-35 35]);

%set(gca,'XLim',[0 60])

set(gca,'XLim',[0 24])

set(gca,'xTick',(0:4:24))

xlabel('GPS Time [hours]')

ylabel('Multipath [cm]')

title (sprintf('GPS L1 [HEL2], G%s, %s', satNo{PRN}, days{n}));

grid minor

legend('CNO','MP')

end

end

%end

%% L2

%for n = 1:7

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 ?

[osasunmwen efosa]

Figured it out. i changed the format. Thanks alot
