It is doable, but your image file names need to be in a sequential order, e.g.: Image1.jpg, Image2.jpg, ...., etc.,
OR IM_01.jpeg, IM_02.jpeg, .., etc., OR IM1.jpg, IM2.jpg,... etc., OR something in a similar fashion.
If this is the case, then you can go ahead; otherwise, you'd need to rename them.
Once you get all your image file names sorted out, you can use something similar to the following type of string conversion procedure to make up the list of your image data file names. E.g.: IM1.jpg, IM2.jpg,... IM13.jpg and import them into MATLAB workspace.
for ii=1:13
MM{ii} =strcat('IM', num2str(ii), '.jpg')
DATA{ii} = imread(MM{ii});
end
Good luck
