I have this sequence:
0 (1) 0 (2) 0 (3) 1 (4) 1 (5) 0 (6) 0 (7) 0 (8) 0 (9) 0 (10) 1 (11) 0 (12)
0 (13) 0 (14) 0 (15) 1 (16) 0 (17) 0 (18) 1 (19) 1 (20).
As I can create an array like this in general, ie can perform instead of substrings of length 3, 4,5,6 .... too long? I have doubt through command for creating the dimension of the matrix, and I want you to believe me automatically. The matrix example is:
0 (18) 1 (19) 1 (20)
0 (15) 0 (17) 1 (19)
0 (12) 0 (15) 0 (18)
0 (9) 0 (13) 0 (17)
0 (6) 1 (11) 1 (16)
0 (3) 0 (9) 0 (15)

Your question is not clear. Is the matrix you want to create always an nx3 size?

A=randi([0 1],1,30); % your array
m=5; % the result will be nx5
n=numel(A);
p=n-m+1:-m:1;
np=numel(p);
B=zeros(np,m);
B(:,1)=p';
mm=m;
for k=2:m
mm=mm-1;
B(:,k)=(n-m+k:-mm:n-m+k-mm*(np-1))';
end
disp(B) % matrix of indices
out=A(B)
