hi;
You can use smthng below;
ie you want to divide the image 4 sub block

| SubBlock1 | SubBlock2 |
------------------------------
| SubBlock3 | SubBlock4 |

[m,n]=size(img);
sub_block1=img(1:m/2,1:n/2);
sub_block2=img(1:m/2,n/2+1:n);
sub_block3=img(m/2+1:m,1:n/2);
sub_block4=img(m/2+1:m,n/2+1:n);
