Solving a Tpye of Fixed-Point Iteration Method

Fixed-Point Iteration method is an important technique to solve nonlinear equations for calculating approximate roots and applied widely.In this paper,we invesitgate on a type of fixed-point iteration method,which dosen't satisfies convergence conditions about iteration method,and propose four iteration methods to solve special equation.We also present an example and its C programme about these iteration methods.At last,we compare convergence speed and analyze the result of these iteration methods.
