how to divide data array into a number of blocks like this using a For Loop?

Please consider this:

 N=16;
 data=[1:N] % original data array 1xN
 nb=[1,2,4,8] % number of data blocks

output: I want to divide my data (1x16) into different blocks=1,2,4,8 like this:

 % output blocks as nob1,nob2,nob4,nob8
 % nob1 is as it is (1x16)
 % All output blocks have same columns (N=16)

i.e.,

 nob1=[1:16] % no division of data

 nob2=[1 2 3 4 5 6 7 8 0  0  0  0  0  0  0  0
       0 0 0 0 0 0 0 0 9 10 11 12 13 14 15 16]

 nob4=[1 2 3 4 0 0 0 0 0 0  0  0  0  0  0  0
       0 0 0 0 5 6 7 8 0 0  0  0  0  0  0  0
       0 0 0 0 0 0 0 0 9 10 11 12 0  0  0  0
       0 0 0 0 0 0 0 0 0 0  0  0  13 14 15 16]

 nob8=[1 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0
       0 0 3 4 0 0 0 0 0 0 0 0 0 0 0 0
       0 0 0 0 5 6 0 0 0 0 0 0 0 0 0 0
       0 0 0 0 0 0 7 8 0 0 0 0 0 0 0 0
       ....
       ....
       0 0 0 0 0 0 0 0 0 0 0 0 0 0 15 16]

Please help me to do so. ( Using a loop for nb=[ 1,2,4,8 ] )

And also the generalized script or function for any value of N (for e.g., N=256 or N=1024)

N=16
nb=[1 2 4 8]
data=1:N
for k=1:numel(nb)
  ii=nb(k);
  v=zeros(ii,N)
  for p=1:size(v,1)
      idx=(p-1)*N/ii+1:p*N/ii;
      v(p,idx)=data(idx);
  end
  out{k}=v;
end

@Azzi: Perfect !
