MATLAB: How to rename files .tif in a folder

movefilerename file

hi.. does anyone can help me with this code, please ? it's created by Jiro Doke. it were run but i didn't get the name file as i want. i wanted to change those file's number into only 1,2,3,4,5,and so on.. FYI, i've tried to change the folder name like this..
% Get all files in the current folder clear all;
files = dir(fullfile('C:\Users\ASUS\Desktop\2','*.tif'));
% Loop through each
for id = 1:length(files)
 % Get the file name (minus the extension)
[~, f] = fileparts(files(id).name);
% Convert to number
num = str2double(f);
if ~isnan(num)
 % If numeric, rename
APath = fullfile('C:\Users\ASUS\Desktop\2', files(id).name);
movefile(APath, sprintf('%d.tif', num));
end
end
and the output files name were like this :
2.100000e+00.tif
2.100100e+00.tif
2.100200e+00.tif
2.100300e+00.tif
2.100400e+00.tif
2.100500e+00.tif
etc..
or if i want to change it like
1a
2a
3a
continue directly to
5b
6b
7b
and so on..
what should i do, please ?
thank you so much.

D = 'C:\Users\ASUS\Desktop\2';
S = dir(fullfile(D,'*.tif'));
for k = 1:numel(S)
    [~,F] = fileparts(S(k).name);
    if ~isnan(str2double(F))
        old = fullfile(D,S(k).name);
        new = sprintf('%d.tif',k)
        movefile(old,new);
    end
end
