摘要 基于密勒法和牛顿法提出一种新的非线性方程求根方法:利用Taylor展开将非线性方程近似为一个二次方程,利用其根构造一种新的迭代方法;并给出其几何意义,理论上证明其局部收敛阶为3阶,数值实验验证了该方法的有效性. A new method of finding the root of nonlinear equation is displayed based on the ideas of Muller and Newton iterative methods.The nonlinear equation is approximated by a quadratic equation where Taylor expansion is applied.The geometrical interpretation is revealed.Finally,the local convergent order is proved to be three,and numerical experiments verify the efficiency of this new method.
