Hi. I have written a function which should return two sequences but it returns only single sequence. I have attached the code below if any one help me in this regard. Thanks in advance

function [X,  Y ]= Hybrid(a,b,w0,s0,c,u);
%a=1.4, b=0.3, wo= 0.1, s0=0.1, c=0.4, u=0.9 
x(1)=0;
y(1)=0;
x0=0;y0=0;
% Initialize
t=0.4-6/(1+x0^2+y0^2);
x(1,1)=1+u*(x0*cos(t)-y0*sin(t));% mu is u
y(1,1)=u*(x0*sin(t)+y0*cos(t));
% Simulate
n=10000;
X1=[];
Y1=[];
for i=2:n
    t=0.4-6/(1+x(i-1,1)^2+y(i-1,1)^2);
    x(i,1)=1+u*(x(i-1,1)*cos(t)-y(i-1,1)*sin(t));
    x_1(i,1)=mod(ceil(abs(x(i))*10000),256);
    %x2_new = unique(x_1,'stable');
    y(i,1)=u*(x(i-1,1)*sin(t)+y(i-1,1)*cos(t));
    y_1(i,1)=mod(ceil(abs(y(i,1))*10000),256);
    %y2_new=unique(y_1,'stable');
    X1=x_1;
    Y1=y_1;
   
 end
plot(x,y,'.','MarkerSize',4)
X=unique(mod(x_1,256),'stable')'; % unique pooints of x chaotic sequence
Y=unique(mod(y_1,256),'stable')'; % unique point of y choatic sequence
  
end
