matlab not reading images from folder in correct sequence

Hi, i have stored the images in a folder by name ex. 1.jpg 2.jpg etc. When i am running the code the matlab doesn't read the images in that sequence. Please help

directory = 'C:\Users\Documents\MATLAB\photos';

files = dir([directory '/*.jpg']);

for i = 1:length(files)

image{i} = imread([directory '/' files(i).name]);

It had happened to me before. The problem is the files name is sorted in according to the strings.

Let's say you have the following images in your folder:

• 1.jpg
• 2.jpg
• ...
• 10.jpg
• 11.jpg

If you run the following code:

for i=1: length(files)
    files(i).name % Shows the name of the files 
end

The output will be:

ans =
    '10.png'
ans =
    '11.png'
ans =
    '1.png'
ans =
    '2.png'
...

If you rename your files as in the following, the files will be sorted correctly:

• 01.jpg
• 02.jpg
• ...
• 10.jpg
• 11.jpg
