y=[];
%for g=1:t
for i=1:r1-r2+1
    for j=1:c1-c2+1
      b1=target(i:i+r2-1,j:j+c2-1);
      y(i,j)=corr2(b1,imcell{d});
      f=max(y); %max row
      [m,u]=max(max(y));%max column

I doubt anyone will take the time until put in more comments to explain the code and you explain "there are something wrong". http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

ok the problem i think in here imcell{d}=imread(fileName); or in the loop before it or may be here y(i,j)=corr2(b1,imcell{d}); please take alook on the code

Please step through it with the debugger and give us all the red error message that you see. You will find out which line it is because it will spew out red when it bombs.
