%This is a sample script file. Type the commands here
% as if you were typing them "live" in Matlab. In
% this example, I'm doing two function iterations, then
% plotting the result with a title and a legend.
x=0.7; %My initial value of x
for k=1:100 %I'm going to do this 100 times
y(k)=x*(1-x); %Do the function, save in an array
z(k)=3.1*x*(1-x);
x=y(k); %Re-set x for the next time around
end
%Since we might print this, use black for plotting
plot(1:100, y, 'k-', 1:100, z,'k-.o');
title('Sample Function Iteration')
legend('x(1-x)','3.1x(1-x)')
