how to protect my code from copying by other users?

 clc,clear
 c=5;
 for N=1:15;

    A=3;B=7;
 if N>=c
  Ixy(N)=A+B*N*N;
 Nc(N)=N;
 fprintf('%d\t   %d\t\t\n',Ixy(N),Nc(N)) 

 elseif  N<5
     Ixy(N)=+B;
     Nc(N)=N;

 fprintf('%d\t%d\t\t\n',Ixy(N),Nc(N))

 end

 end
 N=1:15;
 plot(Ixy(N),Nc(N))
