See the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

Inside your loop you need to save each set of features in an array, like

filePattern = fullfile(myFolder, '*.jpg');
jpegFiles = dir(filePattern);
allImagesFeatures = zeros(length(jpegFiles), 42); % Initialize.
for k = 1:length(jpegFiles)
  baseFileName = jpegFiles(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.
  % Get the 42 features of this image only.
  % You need to custom write AnalyzeSingleImage().
  thisImagesFeatures = AnalyzeSingleImage(imageArray);
  % Append these features to the cumulative array that
  % we are creating to hold features from all the images.
  allImagesFeatures(k, :) = thisImagesFeatures;
end
