Hello!
I have these images in the file.
1.bmp , 2.bmp , ..... , 1000.bmp
i use this command: list = dir('*.bmp');
and the results are
list(1)= '1.bmp' , list(2)='10.bmp' , list(3)='11.bmp', list(4)='12.bmp', list(5)='13.bmp',... .....,list(995)='2.bmp',...
What can i do to put them into the list in ascending order??
list(1)='1.bmp' , list(2)='2.bmp' .....
Thank you very much.

@Nav Desh: go to my FEX submission natsortfiles. Click on the big blue button labeled Download (top right-hand corner). Unzip the zip file into your current directory. Enjoy!
>> 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'

C =
1.bmp10.bmp11.bmp12.bmp
>> [S,INDEX] = sort_nat(C)
Cell contents reference from a non-cell array object.
Error in sort_nat (line 62)
num_val(i,z(i,:)) = sscanf(sprintf('%s ',digruns{i}{:}),'%f');

clear all
clc
Directorio = 'Ruta de guardado de frames';
Frames = dir(fullfile(Directorio, '*.extension'));
Nombres={Frames.name};
[~,name]=sort_nat(Nombres);
%sort_nat es una funcion que se debe descargar y guardar en el mismo directorio donde se ejecuta el programa esta funcion ordena alfanumericamente las palabras incluyendo caracteres especiales.
new_folder=Frames(name);
NumFrames = numel(Frames);
VideoRecuperado = VideoWriter('StegoVideo.mp4','MPEG-4');
VideoRecuperado.FrameRate = FramesRate deseado;
VideoRecuperado.Quality = 80;
open(VideoRecuperado);
for n = 1:NumFrames
full_name= fullfile(Directorio, new_folder(n).name);
I=imread(full_name);
writeVideo(VideoRecuperado, I);
end
close(VideoRecuperado);
