Ok so I have the code intact, I just need to know how to skip the first iteration because using the backwards approximation method will return a NaN on the first iteration. I can't use all the fun stuff like syms, and dsolve and just plop those into the f'(x) in the denominator...
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...
A novel Newton-type n -point iterative method with memory is proposed for solving nonlinear equations, which is constructed by the Hermite interpolation. The proposed iterative method with memory reaches the order ( 2 n + 2 n 1 1 + 2 2 n + 1 + 2 2 n 2 + 2 n + 1 ) / 2 by ...

Newton's method, also called the Newton-Raphson method, is a root-finding algorithm that uses the first few terms of the Taylor series of a function f(x) in the vicinity of a suspected root. Newton's method is sometimes also known as Newton's iteration,
We introduce a new iterative root-finding method for complex polynomials, dubbed {\\it Newton-Ellipsoid} method. It is inspired by the Ellipsoid method, a classical method in optimization, and a property of Newton's Method derived in \\cite{kalFTA}, according to which at each complex number...

This method is not applicable for finding complex, multiple, and nearly equal two roots.This ...
3.Newton’s Method 关于应用Newton法计算一元非线性方程的根已经在《OpenCASCADE Root-Finding Algorithm》中进行了说明,这里要学习下如何使用Newton法应用于多元函数极值的计算。对于一元函数f(x)的求极值问题,当f(x)连续可微时,最优点x满足f’(x)=0。于是当f(x)二次连续可微时,求解f’(x)=0的Newton法为:...
