MATLAB: How to save files using for loop

Question

Hello. So I am trying to save an image using a for loop after I had cropped the image. Though how can I avoid copying and pasting the same code. I want to produce a for loop that will give me the same result as this:

...
cell1= imcrop(I3,stats(1).BoundingBox);
imwrite(cell1,'cell1.tif');
cell2= imcrop(I3,stats(2).BoundingBox);
imwrite(cell2,'cell2.tif');
...

I tried using a for loop but then I wasn't able to change the "i" value in the saved file name. Thank you!

Answer 1

Try this:

for k = 1:10
    img= imcrop(I3,stats(k).BoundingBox);
    imwrite(img,sprintf('cell%d.tif',k));
end

Note how I use the loop variable k to increment both the indexing into the variable stats and also to generate a new filename (using sprintf) with each iteration of the loop.
