MATLAB: SUBSTRINGS CREATION WITH DIFFERENT ORDER

Question

I wish to estimate substrings of length 4-13, a primary secuence currently about 150,000 binary numbers. How to create the substrings be as follows:

let's assume we have the following sequence (numbers in parentheses indicate the order):

s = 0 (1) 1 (2) 1 (3) 0 (4) 1 (5) 1 (6) 0 (7) 1 (8) 0 (9) 0 (10) 0 (11) 1 (12)

substrings of length 4 would be:

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

1 (2) 1 (3) 0 (4) 1 (5)

1 (3) 0 (4) 1 (5) 1 (6)

0 (4) 1 (5) 1 (6) 0 (7)

1 (5) 1 (6) 0 (7) 1 (8)

1 (6) 0 (7) 1 (8) 0 (9)

0 (7) 1 (8) 0 (9) 0 (10)

1 (8) 0 (9) 0 (10) 0 (11)

0 (9) 0 (10) 0 (11) 1 (12) .

Now would do the same with the substrings of length 5 After substrings of length 6 ….. up length 13

Many thanks

Answer 1

s =[ 0  1  1  0  1  1  0  1  0  0 0 1 ];
n=6;
m=numel(s)-n+1;
A=zeros(m,n);
idx=cell2mat(arrayfun(@(x) x:x+n-1,(1:m)','un',0));
out=s(idx)
