MATLAB: How to create overlapping blocks using a matrix rows

arrayblockcellmatrixoverlapping blocks

Hello,
Suppose that we have the matrix A where:
A=[0 1 0 0 1 1 0 1 0 1 0 1 0]
now, we want to create 10 blocks where each block contains four bits and put it in the cell matrix B where:
B= {[0,1,0,0] [1,0,0,1] [0,0,1,1] [0,1,1,0] [1,1,0,1] [1,0,1,0] [0,1,0,1] ...
    [1,0,1,0] [0,1,0,1] [1,0,1,0] }
As you can see, each block is resulted by shifting a sliding window (of size four) by one bit each time, for example:
% the sequence 01001 will gives: 
% [0,1,0,0] and [1,0,0,1]
So how I can implement that?

Try this: 
A=[0 1 0 0 1 1 0 1 0 1 0 1 0];
S = hankel(A, [0 1 1 1]);
S = S(1:10,:);
B = mat2cell(S, ones(1,size(S,1)), size(S,2))';
If you prefer a loop: 
L = 4;
for k1 = 1:numel(A)-L
    S(k1,:) = A(k1:k1+L-1);
end
B = mat2cell(S, ones(1,size(S,1)), size(S,2))';
B{:}                                                           % Display Result (Delete Later)
