You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: CA184rule.m
    path of file: ./repos/Mathematical_Modeling/Cellular automaton/184号和NS规则元胞自动机
    
    the code of the file until where you have to start completion: function CA184rule()
n=1000;
X=rand(1,n)>0.9;
X(n+1)=X(1);
Timestep=500;
data=zeros(Timestep,n);
Y=zeros(1,n);
for j=1:Timestep

    for i=1:n
