For example, i have 5 images of size 512*512 and divided these images into 128*128 blocks/subimages. Here i want to store theses sub-images i.e. 16*5=80 into new folder where each image has 16 sub-images. How i can do it with imwrite commond.
Can you please anyone help me to do it. Thank you in advance

% saving the images first
N = 5 ;
for i = 1:N
I = rand(512,512) ;
I1 = reshape(I,128,128,[]) ;
for j = 1:size(I1,3)
filename = strcat(num2str(N),'_',num2str(j),'.png') ;
imwrite(I1(:,:,j),filename) ;
end
end
% To read the images in the folder
F = dir('*.png'); % your extension of images
for ii = 1:length(F)
I = imread(F(ii).name) ;
end
Combine the above codes. I have saved images using random data as of now. you can call the images using the second code.

yes...change this line:
filename = strcat(num2str(N),'_',num2str(j),'.png') ;
to
filename = strcat(num2str(i),'_',num2str(j),'.png') ;
