I want to save multiple images in a folder?

I made the code but the looping variable comes in the string function so a single image is saved in the folder. Is any other way of separating the looping variable from the colon bars.

img=imread('cameraman.tif');
for i=1:5
   img=imread('http://satellite.imd.gov.in/img/3Dnesec_ir1.jpg')
   imwrite(img,'D:\output database\i.jpg','jpg')% x be a image to write 
end

See https://www.mathworks.com/matlabcentral/answers/57446-faq-how-can-i-process-a-sequence-of-files

for k = 1:5
  FileName = sprintf('D:\\output database\\%d.jpg', k)
  ...
end

This works fine.

for k = 1:5

FileName = sprintf('D:/output database/%d.jpg', k)

...

end

Using fullfile makes the path definition simpler:

for k = 1:5
    FileName = fullfile('D:\output database',sprintf('%d.jpg',k))
    ...
end
