folders = dir("photos");
folders = string({folders.name});
folders = folders(~startsWith(folders,"."))
% Preallocate the structure crashImages
crashImages(length(folders)) = struct("Name",folders(end),"Images",cell(1));
for k = 1:length(folders)
photos = dir("photos\" + folders(k));
photos = string({photos.name});
photos = photos(~startsWith(photos,'.'));
% preallocate the cell array images
images = cell(length(photos),1);
for kk = 1:length(photos)
im = imread("photos\" + folders(k) + "\" + photos(kk));
images{kk} = im;
end
crashImages(k).Name = folders(k);
crashImages(k).Images = images;
clear images
end

Hi, I am wondering if you solved this problem. Because I am also stucked in this section with 99% completion.
This question detail is from the Matlab self-paced course: Matblab Programming Techniques. 4.3 Preallocation: (6/6) Preallocation of Structure and Cell Arrays. task 2.
Preallocate memory for the cell array 'images' that is created within the outer for loop
However I always get error even the official solution is used.

Hi!
I had the same issue and I opened a thechnical support case reporting the problem, and they told me that it was a known issue and that they are working on it.
The solution is to replace every instance of "\" with "/". Thats where the problem is.
Have a nice day.
