Why doesn't my loop code loop?

Here is the code I'm trying to use to generate multiple .jpg images by looping.
for a=11:12:143
data1=data1(:,date1(a:a+11,:));
data2=data2(:,date2(a:a+11,:));
R = corr2(data1,data2);
R_squared = R^2;
figure
scatter(data1,data2)
ylabel('CF (unitless)')
xlabel('AOD')
title('Cloud Fraction Vs Aerosol Optical Depth (Ocean only, -10 <= lat <= 7, 1 deg. Monthly Resolution)')
text(4.5,1, ['R^2 = ' num2str(R_squared)])
axis([0 5 0 1])
grid on
year = a+1990;
print('-djpeg','-r300',sprintf('CF vs. AOD-%d.jpg',year))
end
But instead of 11 images like I'm supposed to get (if you divide distance/step size = (154-11)/11) I only get one, the loop isn't looping. Can anyone help me out here, tell me why??
Thanks!

are you sure that you are holding your plots each time they are outputting and its not just replacing the last plot with a different image every time it goes through the loop?

Worked fine for me, so check this out: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/

It's difficult for us to debug without values for date1 and date2. However now that you know how to debug, you will quickly discover what a and a+11 are, and why one of them is not in the valid index range of date1.
