11.10.2018 · Iteration Method or Fixed Point Iteration. The iteration method or the method of successive approximation is one of the most important methods in numerical mathematics. This method is also known as fixed point iteration. Let f(x) be a function continuous on the interval [a, b] and the equation f(x) = 0 has at least one root on [a, b].

FIXED POINT ITERATION The idea of the xed point iteration methods is to rst reformulate a equation to an equivalent xed point problem: f(x) = 0 x = g(x) and then to use the iteration: with an initial guess x 0 chosen, compute a sequence x n+1 = g(x n); n 0 in the hope that x n! . There are in nite many ways to introduce an equivalent xed point

In numerical analysis, fixed-point iteration is a method of computing fixed points of a function. More specifically, given a function defined on the real numbers with real values and given a point in the domain of , the fixed-point iteration is which gives rise to the sequence which is hoped to converge to a point . If is continuous, then one can prove that the obtained is a fixed point of , i.e.,
