I assume, you want:

top_dir = dir(dir_name);
[dummy, index] = sort([top_dir.datenum]);
top_dir = top_dir(index);

Now the files and folders inside the struct top_dir are chronologically sorted.

Working with relative path names is dangerous. Matlab tries to be smart and searches in all folders of the Matlab path. Better use absolute paths and avoid to append a data folder to the Matlab path:

currentPath = cd;
dir_name = fullfile(currentPath, 'Code');
top_dir  = dir(dir_name);

fullfile is smarter than hardcoding the file separator: 1. it considers existing separators, e.g. in "C:\", and it cares about the preferences of the operating system: \ or /

i think its used to sort the directory. but i need to sort the push buttons in accordance with the folder creation date. can i use the above code for my condition? will it work?

@godwin: The code I have posted sorts the names of the folder according to the dates. Afterwards you create the buttons. And because the names are sorted already, the buttons have the same order also. So there is no reason to sort the buttons. It is not even meaningful to sort the buttons, when the contents of the buttons are sorted already.

Btw. char(Name1(1:end)) can be simplified to Name1.

1. Obtain the creation date of the folders by dir. The replied field datenum is the best value to sort for.
2. Let sort find the wanted order.
3. Set the strings according to this order.

If you need a more explicit implementation, show us, what you have done so far and ask more explicitly for a specific problem.

this is the image of push buttons(folders are showed in push buttons). now i need to sort based on creatied by date of that folders

[Jan]

Where did you get these names from? I guess you use the DIR command, and then you can use the .datenum field directly for sorting also. Please provide the relevant part of the code, because we cannot guess how you create this list of names.

i think this is the answer i found another site after line 29 add this code. i think it will help for others too.

if true
  %%sort push buttons
Afields = fieldnames(top_di);
Acell = struct2cell(top_di);
sz = size(Acell);
Acell = reshape(Acell, sz(1), []);
Acell = Acell';
Acell = sortrows(Acell, 2);
Acell = reshape(Acell', sz);
top_dir = cell2struct(Acell, Afields, 1);
end
