牛顿迭代法(Newton’s method)又称为牛顿-拉弗森方法(Newton-Raphson method),它是一种在实数域和复数域上近似求解方程的方法。方法使用函数的泰勒级数的前面几项来寻找方程的根。 参考链接: 用python算微积分及牛顿迭代求解高阶方程 牛顿迭代法基本思想 考察一般形式的函数方程f(x)=0,首先运用校正技术建立迭代公式...
Newton-Raphson methodsubroutine INVNewton-Raphson method can be used to solve the elastohydrodynamic lubrication (EHL) problem in the line contact. One of the advantages of the Newton-Raphson method is that if the initial solution is close enough to the real solution, its converging process is ...
牛顿法又叫做牛顿-拉裴森(Newton-Raphson)方法,是一维求根方法中最著名的一种。其特点是在计算时需要同时计算函数值与其一阶导数值,从几何上解释,牛顿法是将当前点处的切线延长,使之与横轴相交,然后把交点处值作为下一估值点。 图1 从数学上解释,牛顿法可以从函数的泰勒展开得到。\(f(x)\)的泰勒展开可以表示...
