PROBLEM WITH CREATION SUBSTRINGS IN ARRAY

Very good, I, for example I have a string like this:

s = [0 1 0 0]

and I use the following code for creating substring length = 3

if true

    % code

n=3;

m=numel(s)-n+1;

A=zeros(m,n);

idx=cell2mat(arrayfun(@(x) x : x+n-1,(1:m)','un',0));

out=s(idx);

[a,b,c]=unique(out,'rows','stable');

end

The substrings are created as follows:

s = [0 (1) 1 (2) 0 (3) 0 (4)]

1-0 (1) 1 (2) 0 (3)

2-1 (2) 0 (3) 0 (4)

The substrings are always created in this way.

The problem arises when I want to calculate the substrings in an array:

s = [0 1 0 0; 1 1 0 0]

How I can do?

What is the expected result?

[Azzi Abdelmalek]

s = [0 1 0 0; 1 1 0 0]
n=3;
m=size(s,2)-n+1;
idx=cell2mat(arrayfun(@(x) x : x+n-1,(1:m)','un',0));
M=[];
for k=1:size(s,1)
  ss=s(k,:);
  M=[M; ss(idx)];
end
M=unique(M,'rows','stable')
