im=imread('pout.tif');
n=size(im,1);
m=size(im,2);
dl=3   ; % number of vertical portions
dc=2  ; % number of horizontal portions
a=fix(n/dl);
b=fix(m/dc);
n0=1;
portion=[];
ii=0;
for k=linspace(a,n,dl)
  m0=1;
  ii=ii+1;
  jj=0;
  for p=linspace(b,m,dc)
      jj=jj+1;
      im1=im(n0:k,m0:p,:);
      portion{ii,jj}=im1;
      m0=p+1;
  end
  n0=k+1;
end
portion

but the image is not displayed,has the image been divided into blocks

[Azzi Abdelmalek]

To display your portions

ii=0;
for k=1:dl
  for p=1:dc
      ii=ii+1;
      subplot(dl,dc,ii);
      imshow(portion{k,p});
  end
end
