Thanks for yours answers.
How can I save all the images this image directory on a two-dimensional array as input to train neural networks?

I = dir('*.jpg'); % or jpeg or whatever.
for ii = 1:length(I)
C{ii} = imread(I(ii).name); % Store in a cell array.
end
Now the first image is stored as C{1}, the second as C{2}, etc...

this is my code:
myFolder = 'Tapmau';
filePattern = fullfile(myFolder, '*.bmp');
bmpFiles = dir(filePattern);
for k = 1:length(bmpFiles)
baseFileName = bmpFiles(k).name;
fullFileName = fullfile(myFolder, baseFileName);
% fprintf(1, 'Now reading %s\n', fullFileName);
imageArray = imread(fullFileName);
% imshow(imageArray); % Display image.
% drawnow;
% Force display to update immediately.
end
for i=1:length(bmpFiles)
baseFileName=bmpFiles(i).name;
fullFileName = fullfile(myFolder, baseFileName);
image=reshape(imageArray,[],1)
end
