How to load images from variable

Hello. I used this code to load images from folder to matlab. It worked well, but i don´t know how to load for example 3. and 5.(it doesn´t matter which one) image from imageArray and show it by figure...so how are images indexed in imageArray? please give me some simple example. i am begginer. thank you

myFolder = 'C:\Users\lukino\Pictures\...';
if ~isdir(myFolder)
  errorMessage = sprintf('Error: The following folder does not exist:\n%s', myFolder);
  uiwait(warndlg(errorMessage));
  return;
end
filePattern = fullfile(myFolder, '*.jpg');
jpegFiles = dir(filePattern);
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.
end

Look like code from the FAQ. What's the problem? What are examples 3 and 5? imageArray is not indexed. It's overwritten each iteration. You read in that image, process it, and then you're done and you move on to the next image.

yes it is from FAQ. I need to compare images, so i thought that by this code i can load all images from folder, and i can compare images. so how to make varriables for every image in loop? it is possible to index "imageArray" and how?

ok a did it..som simple...

imageArray = imread(fullFileName);
  ** *x{k}=imageArray;* **
  imshow(imageArray);  % Display image.

still, thank you :)

I would not do it that way as it's wasteful of memory. I'd call a function like AnalyzeSingleImage(imageArray) inside the loop. I don't see any need to read all of the images into a cell array and then you'll just have to have another loop after that to process them all after extracting from "x". I have no idea why you're wanting to save all of these images in an "x" array - it doesn't seem necessary to me.
