How can I randomize the order of a matrix of images

I have a 2x2 matrix (four images total, same size) that I need to randomize each time the code is ran. I tried using randperm but I can't seem to get the randomized numbers (1-4) to be indexed to the image file names.

What code did you use?

[Beyza Kural]

IMAGESTORE = {queen,stark,hound,imp} %names of the images (queen,stark,hound,imp)

col= size(IMAGESTORE,2)

random = randperm(col)

new = IMAGESTORE(:,random)

the variable new gives me the dimensions on the images, not the actual images.

 Filenames = compose('image%d.png', 1:4);
 Filenames(randperm(numel(Filenames))) % ?

What does "compose" do? and what is "Filenames" in the second line used for?

[madhan ravi]

I have no clue what you want to do. The Filenames in the second line was just used to illustrate reordering the Filenames in a random manner.

[Beyza Kural]

IMAGESTORE = {queen,stark,hound,imp} %names of the images (queen,stark,hound,imp)

col= size(IMAGESTORE,2)

random = randperm(col)

new = IMAGESTORE(:,random)

This is what I did so far and it does randomize but it doesn't index the actual images so that they can be displayed.

[madhan ravi]

 for k = 1:numel(new)
     I = imread(new{k});
     figure(k)
     imshow(I)
 end

random is a built-in function. I'd call it something different, like sortOrder:

IMAGESTORE = {queen,stark,hound,imp} %names of the images (queen,stark,hound,imp)
numImages = length(IMAGESTORE)
sortOrder = randperm(numImages) % 1 to 4 in a scrambled order.
 for k = 1 : numImages
     % Get image array from the cell array.
     thisImage = IMAGESTORE{sortOrder(k)};
     % Display image.
     imshow(thisImage);
     % Now do other stuff with thisImage.
 end

Thank you sir Image Analyst!

thank you this helps.
