quad_it(x,a,maxstep) computes the quadratic iterator
given by the equation f(x) = ax(1x).
quad_diff(a,maxstep) computes and shows the difference between two quadratic iterators starting with two slightly different starting points.
x is the vector of starting points;
a is the parameter used above;
maxstep the number of iterations.
quad_it uses x = [0.2 ... 0.22], a = 4, maxstep = 5.
quad_diff uses a = 4, maxstep = 80.
