folderName = 'C:\Users\Shruthi\Desktop\project\A data\SegmentedCharacters'; 
Imgs = dir(fullfile(folderName, '*.jpg'));
C={Imgs.name};
cx=natsortfiles(C)
q=1;

natsortfiles can now sort the DIR structure directly:

>> S = dir('*.txt');
>> S.name
ans =
    '1.txt'
ans =
    '10.txt'
ans =
    '2.txt'
>> S = natsortfiles(S); % alphanumeric sort by filename
>> S.name
ans =
    '1.txt'
ans =
    '2.txt'
ans =
    '10.txt'
