save sequence of images in a folder using matlab -

i want save images folder. tried code given below

      [ilabel num] = bwlabel(if); disp(num); iprops = regionprops(ilabel); ibox = [iprops.boundingbox]; ibox = reshape(ibox,[4 83]);  figure,imshow(ibox);   n=1:num         [r,c] = find(ilabel==n);         % extract letter         n1=iout(min(r):max(r),min(c):max(c));           % resize letter (same size of template)         img_r=imresize(n1,[42 24]);         %figure,imshow(n1);         %uncomment line below see letters 1 one          %imshow(img_r);pause(0.5)  imwrite(img_r,['h:\\mainproject\\codes\\images\\test0.jpg' ]);  end    

but last letter saved in folder. dont know made mistakes.i tried lot didn't it.please me , in advance

i think may overwriting images, since using same name test0.jpg. try:

[ilabel num] = bwlabel(if); disp(num); iprops = regionprops(ilabel); ibox = [iprops.boundingbox]; ibox = reshape(ibox,[4 83]); figure,imshow(ibox);   n=1:num         [r,c] = find(ilabel==n);         % extract letter         n1=iout(min(r):max(r),min(c):max(c));           % resize letter (same size of template)         img_r=imresize(n1,[42 24]);         %figure,imshow(n1);         %uncomment line below see letters 1 one         %imshow(img_r);pause(0.5)         image_name = strcat('h:\\mainproject\\codes\\images\\test', num2str(n), '.jpg');         imwrite(img_r,[image_name]);  end 

i can't test now, , couldn't comment (points below 50). hope helps,
