牛顿迭代法求解非线性方程组
说明: 牛顿法又称牛顿-拉弗森方法(Newton-Raphson method),是一种在实数域和复数域上近似求解方程的方法。本程序收敛速度快,迭代步数可取大一些(Newton method, also known as Newton-Raphson method, is an approximate method for solving equations in real and complex fields. The program has fast convergence speed so the number of iteration steps can be larger.)
