How do I subplot multiple tiles that I divided from a satellite image in one figure?

I have to divide my satellite image into 256 tiles of 500 by 500 pixels. I use mat2cell function to do that. After that I want to see the result by displaying in one figure.

Please help me figure out how to subplot it!

Here is my code :

tiles=zeros(500,500);
tiles = mat2cell(TOARef_B{5}, [500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 261], [500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 101]);
for m=1:16
    for n=1:16
        subplot(16,16,256); imshow(tiles{m,n});       
    end
end

Hi Oanh,

You can try the following, since you are there are 16 x 16 tiles.

tiles=zeros(500,500);
tiles = mat2cell(TOARef_B{5}, [500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 261], [500 500 500 500 500 500 500 500 500 500 500 500 500 500 500 101]);
k = 1; % to index the subplot
for m=1:16
    for n=1:16
        subplot(16,16,k); imshow(tiles{m,n});
        k = k+1;
    end
end

Note, this will create very small sub-tiles since the size is 256.

Hope this helps.

count = 0 ; 
for m=1:16
    for n=1:16
        count = count+1 ; 
        subplot(16,16,count); imshow(tiles{m,n});       
    end
end

Read about montage. This would be better.

I think they're recommending imtile() over montage().
