Create a single 4D uint array from a image folder

Hi everyone,

i have an image dataset with different classes (image, depth, labels, normal ... etc) and they all have their own folders.

i want to create a .mat file in which each of these folders are one single 4D uint arrays.

for example i want a image array with the following dimensions: 480 x 640 x 3 x 1000 that represents just one folder of the dataset (like image)

i have tried using "cat" but i could not make it work in a loop.

id appreciate a bit of help since im very new to matlab.

Example

n = 10;            % number of images
I_many = zeros(480, 640, 3, n);
for i = 1:n
    s = sprintf('Folder%d/image.png',i);        % path to image
    I = imread(s);
    I_many(:,:,:,i) = I;
end
