hello, im using the following code :

folderName = 'C:\Users\Shruthi\Desktop\project\A data\SegmentedCharacters'; 
Imgs = dir(fullfile(folderName, '*.jpg'));
C={Imgs.name};
cx=natsortfiles(C)
q=1;
for blah blah
Img = imread(fullfile(folderName, cx(q).name));  % Read image
        q=q+1;
blah blah
end

but it gives me this error

Improper index matrix reference.
Error in Untitled5 (line 142)
        Img = imread(fullfile(folderName, cx(q).name));  % Read image

could anyone tell me how i can rectify this? Thank you!

在 MATLAB Online 中打开

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'
