摘要
对求解非线性方程组的Newton迭代法进行改进 ,放宽了对其迭代函数的限制 ,并对改进后的迭代法的收敛性进行了严格的证明 ,为进一步设计出成本低且收敛速度较慢的迭代法提供了理论依据 .
Newton iteration method for solving the system of no nlinear equations is improved, restriction on its iteration function is relaxed, the convergence of the improved iteration algorithm is proved strictly, and the theoretical basis for designing cheaper and faster iteration methods is supplie d.
