x n+1=4rx n(1-x n)
r = 0.2
x = 0.6
x0 = ones(0,30);

I have declared all of my variables but loop is not working. Should I be using iteration? Can someone please help me.

EDU>> x0 = ones(0,30);
for i = x0 +1; i=30
  x0 = 4*r*x*(1-x)
end

Thank you very much. That worked perfectly. How am on to plotting the points. I have a lot to learn about programming.

Your loop is not working for a number of reasons. Is the following what you have in mind?:

 n = 30;
 r = 0.2;
 x = zeros(1,n+1);
 x(1) = 0.6;
 for i = 1:n
  x(i+1) = 4*r*x(i)*(1-x(i));
 end
