MATLAB: Titling figures from 1 till 20.

Question

I am plotting 20 figures on one big figures. I need to title each image by "image i", so that 'i' is 1,2,3….20 depending on the order of image. (example: 'image 1', 'image 2', 'image 3'…. 'image 20')

Does anybody know how to make it?

Here's the code:

   while i<20
        j=i+1;
        f_c5_diff(j,:)=abs(f_c5(j,:)-f_c5(1,:));   
        f_c13_diff(j,:)=abs(f_c13(j,:)-f_c13(1,:));  
        subplot(5,4,j)
        plot(F,f_c5_diff(j,:),'r')
        hold on
        plot(F,f_c13_diff(j,:),'b')
        hold off
        xlabel('Frequency (HZ)')
        ylabel('Amplitude (uV)')
        title ('image')
        i=i+1;
   end

Thanks, Marwan
