how to combine the blocks

clc
clear all
x= 

[2 3  4 5

   2 3  4 5

   1 2  3 4

   1 2  3 4]

[r c]=size(x);
bs=2; % Block Size (8x8)
nob=(r/bs)*(c/bs); % Total number of 8x8 Blocks

% Dividing the image into 2x2 Blocks

kk=0;
for i=1:(r/bs)
for j=1:(c/bs)
Block(:,:,kk+j)=x((bs*(i-1)+1:bs*(i-1)+bs),(bs*(j-1)+1:bs*(j-1)+bs));
BlockM=Block(:,:,kk+j);
  BlockMM=mean(BlockM(:));
  Block(:,:,kk+j)=BlockMM
end

kk=kk+(r/bs);

end

i have divided the matrix into blocks of 2x2 size and i have stored it in Block(:,:,i) separately. can any one please help me to combine into original matrix thanks in advance
