Odd numbering of files from one folder to other in matlab

Files present in one folder:

1 copy(1).jpg,

1 copy(2).jpg

.......

1 copy(800)

Odd numbering of files and save it in other folder.Desired output shown below:

1.jpg,

3.jpg,

5.jpg

....

799.jpg

Source code i tried:

a ='C:\Users\rahul\Desktop\jumbled test\copiedimages\';
A =dir( fullfile(a, '*.jpg') );
fileNames = { A.name };
for iFile = 1 : numel( A )
  newName = fullfile(a, sprintf( '%d.jpg',iFile+2) );
  movefile( fullfile(a, fileNames{ iFile }), newName ); 
end

But i cant able to get desired output.So what will be the solution?

Solution

Don't rename the files, just move them to the new directory after checking if they had an odd number in their file name:

a ='C:\Users\rahul\Desktop\jumbled test\copiedimages\';
destination = a ='C:\Users\rahul\Desktop\jumbled test\copiedimages\Odd\';
A =dir( fullfile(a, '*.jpg') );
fileNames = { A.name };
for iFile = 1 : numel( A )
    [~,name] = fileparts(fileNames{ iFile });  %// This part might not be necessary if fileNames{ iFile } is just the file name without the directory. In that case rather use name=fileNames{ iFile };
    %// Extract the number from the file name
    filenum = str2num(name(8:end-4));
    %// Check if the number is odd
    if mod(filenum,2) == 1 
        movefile(fullfile(a, fileNames{ iFile }), fullfile(destination, fileNames{ iFile }));
    end
end
