how do i sort images into a list in ascening order

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.

You could download my FEX submission natsortfiles:

>> 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'

@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'

thank you very much,the sort_nat is my answer,but i cant understand the syntax.

I downloaded the sort_nat.m but i cant find what is the syntax.any help?

sort_nat(list) %error

sort_nat([list.name]) %error

[alex]

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');

[alex]

ok found it

list = dir('*.bmp'); C={list.name} sort_nat(C)

thank you very much!

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);
