how to generate ZCZ sequences

hello can you help me on how to generate zcz (zero correlation zone ) i tried this code but it does not work

% Golay complementary pair

Z0 = [-1 -1 1 -1 -1 -1 -1 1];

Z1 = [-1 1 1 1 -1 1 -1 -1];

% Starter matrix Z(0,0)

Z = [Z0; Z1];

% ZCZ parameters

N = 8; % Code length

K = 2; % Number of codes

Z0_length = 2; % Zero-zone length

% Generate ZCZ sequences

for n = 1:N

Z = [Z, Z.*repmat(Z(:,1), 1, size(Z, 2))];

end

% Increase the number of codes

Z = [Z, Z, Z, -Z];

% Display the ZCZ sequences

disp(Z);
