How to save each data from for loop

I have a for loop(last for loop), but every character overwrites and I have only the final data left.
[L Ne]=bwlabel(imagen);
%%Measure properties of image regions
propied=regionprops(L,'BoundingBox');
hold on
%%Plot Bounding Box
for n=1:size(propied,1)
rectangle('Position',propied(n).BoundingBox,'EdgeColor','g','LineWidth',2)
end
hold off
pause (1)
%%Objects extraction
figure(3)
for n=1:Ne
[r,c] = find(L==n);
n1=imagen(min(r):max(r),min(c):max(c));
%imshow(~n1);
pause(0.5)
end

What is imagen()? Is it your own function. In any case refer to my answer below.

Easiest solution is to save each in cell array since the subsets can all be differing sizes can't just store as planes in 3D array...
IMAGES=cell(Ne,1); % create a cell array of proper size
for n=1:Ne
[r,c] = find(L==n);
IMAGES(i)={imagen(min(r):max(r),min(c):max(c))}; % store each 2D array in nth cell
%imshow(IMAGES{n});
pause(0.5)
end

Change your last for loop as follow
n1 = []
for n=1:Ne
[r,c] = find(L==n);
n1 = [n1 imagen(min(r):max(r),min(c):max(c))];
%imshow(~n1);
pause(0.5)
end
n1 will save all the values.

You have my permission to do so, yes... :)
Good plan to follow "best practices" in avoiding these kinds of what_seem_so_easy_to_do techniques, but the short-term gratification leads to longer-term misery when get to anything but the most trivial of applictions--best to learn to avoid altogether while learning; then with time one can recognize when it is time to break the rule for a specific purpose (altho that's not that common, it does occur).
