Saving a subplotted blocks in one image with 6 split parts

imwrite(img, 'DEN.bmp');
bmp = imread('DEN.bmp');
[Matrix Map] = imread('DEN.bmp');
imshow(Matrix, Map);
[Row Col Layer] = size(bmp);

bmp = imread('DEN.bmp');
blocks = mat2cell(bmp, size(bmp,1)/2*ones(1,2), size(bmp,2)/3*ones(1,3), 3);
count = 1;
for i=1:size(blocks,1)
    for j=1:size(blocks,2)
        subplot(2,3,count)
        imshow(blocks{i,j});
        count = count + 1;
    end
end

my question is if i use one image in a subplot to have 6 split parts in a block. how can i save them separately in an separate image format. i already forgot how to do this. i only have one image file called DEN.bmp .

I'm going to assume your image isn't an indexed image. If it is, you'll have to carry the map around too.

bmp = imread('peppers.png');
blocks = mat2cell(bmp, size(bmp,1)/2*ones(1,2), size(bmp,2)/3*ones(1,3), 3);
count = 1;
for i=1:size(blocks,1)
    for j=1:size(blocks,2)
        subplot(2,3,count)
        imshow(blocks{i,j});
        count = count + 1;
        
        imwrite(blocks{i,j},sprintf('subblock_%d_%d.png',i,j))
    end
end
