Fixed-point iteration is an iterative numerical method used to find solutions of equations of the form $$x = g(x)$$, where the goal is to converge to a fixed point that satisfies the equation. This technique is central to iterative methods as it provides a straightforward way to approximate roots or solutions by repeatedly applying the function $$g$$ to an initial guess until the values stabilize within a desired tolerance. The success of this method relies heavily on the properties of the function and the choice of the initial guess.
congrats on reading the definition of Fixed-point iteration. now let's actually learn it.
