摘要 提出一个新的求解非线性方程组的迭代方法,证明了这种方法是3次收敛的,并给出5个数值实验,从迭代次数、所用CPU时间、误差以及收敛阶数4个方面,将新算法与经典的牛顿法等5个算法进行比较,数值实验表明该算法是有效的. A new iterative method for solving systems of nonlinear equations is presented. The proposed method is proved to be cubic convergent. In addition, five numerical examples are given to illustrate the efficiency and the performance of the newly developed method, which confirm the good theoretical properties of the approach.
