在维基百科中的定义如下: In numerical analysis, Newton's method (also known as the Newton–Raphson method), named after Isaac Newton and Joseph Raphson, is a method for finding successively better approximations to the roots (or zeroes) of a real-valued function. It is one example of a root...
牛顿迭代法(Newton’smethod)又称为牛顿-拉夫逊(拉弗森)方法(Newton-Raphsonmethod),它是牛顿在17世纪提出的一种在实数域和复数域上近似求解方程的方法。 我想你可能只看得懂这个是牛顿提出的吧,其实它是牛顿解复杂方程的方法,通常这类方程没有求根公式,不像一元二次方程有...

Code: function [ y,f,f2 ] = derivf2(x) syms t f2=exp(t)-4.*t.^2; f=@(t)diff(f2); y=eval(subs(f,t,x)); end My question is. How do I code the actual method on Matlab itself? I've tried several times, but I ran across some problems. My intention isn't to have th...
牛顿迭代法(Newton's Method) 简介 牛顿迭代法(简称牛顿法)由英国著名的数学家牛顿爵士最早提出。但是,这一方法在牛顿生前并未公开发表。 牛顿法的作用是使用迭代的方法来求解函数方程的根。简单地说,牛顿法就是不断求取切线的过程。 对于形如f(x)=0的方程,首先任意估算一个解x0,再把该估计值代入原方程中。
