With the newer versions of matlab, if you just want to save one of the subplots to a file:
h=subplot(2,1,1);
plot(1:10);
myAxes=findobj(h,'Type','Axes');
exportgraphics(myAxes,'myFile.pdf');

Do you want save it as one image or two separately images?
If one: use print
If two: copy each plot to new figure ( copyobj ) and then print.

This has been asked before: http://www.mathworks.co.uk/matlabcentral/answers/12111-printing-axes
You can use export_fig from the FEX http://www.mathworks.com/matlabcentral/fileexchange/23629-exportfig
or do something like
figure;
subplot(2,2,1);
plot(1:10);
hax = subplot(2,2,2);
plot(1:5);
Make a new figure, copy the axis to it, scale the axis to be the "full" size, and print it.
hfig = figure;
hax_new = copyobj(hax, hfig);
set(hax_new, 'Position', get(0, 'DefaultAxesPosition'));
print(hfig);
If you want a jpg, od:
print(gcf, '-djpeg', 'myfigure')

If you want a jpg (you should edit your question to include this information) just add the jpg flag ... (see my edited answer).
