See the FAQ for 2 different ways of doing it: http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F

i think i solved the problem by putting
figure(k);
subplot(3,3,1);
imshow(image1);
subplot(3,3,2);
imshow(image2);
subplot(3,3,3);
imshow(image3);
subplot(3,3,4);
imshow(image4);
subplot(3,3,5);
imshow(image5);
subplot(3,3,6);
imshow(image6);
subplot(3,3,7);
imshow(image7);
subplot(3,3,8);
imshow(image8);
subplot(3,3,9);
imshow(image9);
--------------------------------------------------------------
now it shows all segmented images but how can i store each part and extract features for them and store them in good dataset for classification?
-------------------------------------------------------------------
i could make this instruction it will extract features for image1 for all 20 images but i need it for all 9 parts(image1...image9)
% Extract the 9 images.
image1 = imageArray(1:r3, 1:c3);
GLCM = graycomatrix(image1,'Offset',[0 2]);
Resultstats = graycoprops(GLCM,{'energy','Homogeneity'})
image2 = imageArray(1:r3, c3+1:2*c3);
image3 = imageArray(1:r3, 2*c3+1:end);
image4 = imageArray(r3+1:2*r3, 1:c3);
image5 = imageArray(r3+1:2*r3, c3+1:2*c3);
image6 = imageArray(r3+1:2*r3, 2*c3+1:end);
image7 = imageArray(2*r3+1:end, 1:c3);
image8 = imageArray(2*r3+1:end, c3+1:2*c3);
image9 = imageArray(2*r3+1:end, 2*c3+1:end);
