I am using following code to read multiple images from a source folder, rotate them and save in target folder. However the images are not read in same sequence as they are in source folder. I want the images to be processed one by one in sequence from source folder. Can anyone please help me to identify the issue with this code.

folder = 'E:\Source folder\';
filePattern = fullfile(folder, '*.png');
myFiles = dir(filePattern);
for k = 1 : length(myFiles)
    fullFileName = fullfile(myFiles(k).folder, myFiles(k).name);
    imageArray = imread(fullFileName);   
    I1=(imageArray);
    figure
    imshow(I1);
    I2=I1';
    figure
    imshow(I2);
    Res='E:\target folder';
    mkdir(Res);
    baseFN= sprintf('%d.png',k);
    fullFileName = fullfile(Res,baseFN)
    imwrite(I2,fullFileName);
end

Have a look on this file exchange function: natsort

在 MATLAB Online 中打开

folder = 'E:\Source folder\';
filePattern = fullfile(folder, '*.png');
myFiles = dir(filePattern);
myFiles = sort({myFiles.name});
for k = 1 : length(myFiles)
    fullFileName = string(fullfile(folder, myFiles(k)));
    imageArray = imread(fullFileName);   
    I1=(imageArray);
    imshow(I1);
    I2=I1';
    imshow(I2);
    Res='E:\target folder';
    mkdir(Res);
    baseFN= sprintf('%d.png',k);
    fullFileName = fullfile(Res,baseFN);
    imwrite(I2,fullFileName);
