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...
你的导数计算有点问题-你忘记了f(x+h)和f(x-h)之间的差的括号：
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-finding algorithm. ...

用MATLAB实现一个Newton-Raphson求解器(三) 在前两期中,我们已经实现了基本的Newton-Raphson算法,并且实现了自动计算给定函数的导数。 但是,很明显,代码还不够易用。 毕竟,每次使用都需要写一遍迭代过程,显然是非常麻烦的,更算不上是一个求解器。 所以,下一个目标就是将整个求解过程包装成一个函数,只需要给出...
