Regarding Plotting

I have 9 years pollution data and I would like to plot monthly maps. I have code those can process all data, but I do not know how to save each and every image (jpg,pdf). It will be nice if somebody can tell me how to fix this problem.

Look in the documentation:

help saveas
help print
help imwrite

do I need to write loop for saving all images ?

my codes are

for i=1:length(dir_list)

if strfind(dir_list(i).name,'2003')==19

data=dlmread(strcat(path,dir_list(i).name),'',55);

end

latitude=data(:,7);

lon_t=data(:,8);

longitude=rem((lon_t+180),360)-180

co=data(:,38);

figure(1)

load coast

h1=axesm('MapProjection','eqdcylin',... % There are many different map projections available. I don't claim this is the best.

'Grid','off',... % The default is to have a grid over the whole map, which I usually get rid of.

'MapLatLimit',[15-d_deg/2 45+d_deg/2],... %This defines the latitude and longitude limits of the plot. These include the whole globe

'MapLonLimit',[(-105-d_deg/2) (-75+d_deg/2)],...

'MeridianLabel','off',... %This turns off the meridian labels altogether

'Frame','on'); %This turns off the frame around the whole plot.

plotm(lat,long,'k')

hold on

tightmap on

colormap(jet);

grid on

h=surfacem(latgrid,longrid,grid_ch4);

colorbar

% legend('show')

xlabel('Longitude');

ylabel('Latitude');

title('SCIAMACHY XCH4 Jan 2003');

saveas(h1,'jpg');

I wanted to save every month image separately and I have give them different name too for e.g Jan 2003 , March 2004 ..
