MATLAB: How to save save split images in multiple filenames

Question

I have a code which shows the multiple images of a scanned *.tif document.

for i=1:5
    d=imshow(imread('gi2.tif',i));
    figure;
end

I need to save these images as multiple files. I used the following code for that:

basename='im_'
for i=1:5
    d=imshow(imread('gi2.tif',i));
    figure;
    filename=[basename,num2str(i)];
end

But the code is just creating a variable filename with data im_5. I also tried using "sprintf" using the following code:

for i=1:5
    d=imread('gi2.tif',i));
    filename=sprintf('im_%d.jpg',i)
end

But this basically prints the filename im_<no.> and nothing else.

Please support!!

Answer 1

That solves your problem?

for i=1:5
    imwrite(imread('gi2.tif',i),['im_' num2str(i) '.tif']);
end
