%This script file shows how to create a cobweb diagram using the functions
%cobweb.m and iterates.m.  Here, we will create a cobweb diagram of the
%logistic function with a starting point of 0.2 and plot the first five
%points of the orbit on the interval (0,1).


%First, define the function. This is different than before, when we used a
%function file.  If the function is small, we don't need a separate file:
logistic=@(x) 3.*x.*(1-x);

%Now call the cobweb function.  Notice the input arguments are
%  Function name, starting point, number of iterates,
%  interval endpoints:
cobweb(logistic, 0.2, 5, 0, 1);
