How to generalize the fixed point iteration

  1. Aug 14, 2012 #1
    If we want to solve $$f(x)=0$$ we can re-write the equation as
    $$g(x)=x$$ and use the fixed point method, i.e, $$x_{n+1}=g(x_n)$$ starting with a guess $$x_0.$$ I was wondering if something similar can be done with

    Yes, of course. Just think of (x, y) as a single two dimensional variable, z and solve g(z)= z.
