saving images as a database

I am trying to put a folder of jpg images in a database .mat i tried this from similar stuff that i googled, i was successful doing it to one image using

save('test.mat','f')

here is the failed code,

if true
  srcFiles = dir('F:\matlab\face\data\*.jpg') % the folder images are in
for i = 1 : length(srcFiles)
  filename = imread(['F:\matlab\face\data\',srcFiles(i).jpg]);
  holdImage(i) = imread(filename);

end save('testimagebase.mat','holdImage'); end

Try this snippet. Set folder to:

folder = 'F:\matlab\face\data';
ListOfImageNames = {};
ImageFiles = dir([folder'/*.*']); % Get all files.
for Index = 1:length(ImageFiles)
  baseFileName = ImageFiles(Index).name;
  [folder, name, extension] = fileparts(baseFileName);
  extension = upper(extension);
  % Let's save just those we are interested in:
  switch lower(extension)
  case {'.png', '.bmp', '.jpg', '.tif', '.avi'}
    % Allow only PNG, TIF, JPG, or BMP images
    ListOfImageNames = [ListOfImageNames baseFileName];
  otherwise
  end
end
% Now ListOfImageNames is a list of all image format files.
% Now do whatever you want with that list.

Try just this inside your loop:

   holdImage(i) =  imread(['F:\matlab\face\data\' srcFiles(i)],'jpeg');
