How to draw pareto front of my given code

Please help me to find pareto front of given objective functions. I am beginner in matlab so please give little explanation. If my question is not clear please let me know I will more explain. thanks

function [f]=task1(x) 
clc
i=1;
pop_size=100;
V=13;
y=randi([0 1],pop_size,V);
y(:,2)=~y(:,1);
y(:,3)=~y(:,4);
y(:,5)=~y(:,6);
y(:,12)=~y(:,13);
 while i:pop_size
  x=y(i,:);
  f(1)=15*x(1)+20*x(2)+30*x(3)+25*x(4)+40*x(5)+35*x(6)+35*x(7)+50*x(8)+20*x(9)+23*x(10)+30*x(11)+45*x(12)+50*x(13);
  y(i,V+1)=f(1);
  f(2)=5*x(1)+3*x(2)+4*x(3)+5*x(4)+4*x(5)+6*x(6)+5*x(7)+8*x(8)+5*x(9)+3*x(10)+2*x(11)+7*x(12)+6*x(13);
  y(i,V+2)=f(2);
  f(3)=6*x(1)+4*x(2)+2*x(3)+2*x(4)+3*x(5)+4*x(6)+4*x(7)+4*x(8)+2*x(9)+3*x(10)+3*x(11)+4*x(12)+3*x(13);
  y(i,V+3)=f(3);
  f(4)=2048*x(1)+1024*x(2)+256*x(3)+512*x(4)+256*x(5)+512*x(6)+1024*x(7)+1024*x(8)+512*x(9)+512*x(10)+256*x(11)+1024*x(12)+512*x(13);
  y(i,V+4)=f(4);
  a= [y(i,[14 15 16 17])];    
  i=i+1;
 end
end
