Newton-Raphson method is the simplest among all root finding algorithm, which is illustrated to find roots of a simple polynomial X*X-7=0. Ref [1]: http://www.math.colostate.edu/~gerhard/classes/331/lab/newton.html Ref [2]: http://en.wikipedia.org/wiki/Newton's_method 인...
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. 牛顿...
Two methods for obtaining numerical solutions, a generalized Newton-Raphson root finding algorithm and the Davidson-Fletcher-Powell gradient search method, are compared for accuracy and efficiency. An extensive sensitivity analysis is performed ... SS Sunder,RA Sanni - 《Applied Ocean Research》 被引...

Consider an application that finds the intersections of two equations: y = ex y = mx + c The design finds the roots of the equation, ex- mx - c = 0, using Newton-Raphson iteration. The Newton-Raphson part of the design derives an improved approximation to the root from the previous ...
牛顿法(Newton’s method)又称为牛顿-拉弗森法(Newton-Raphson method),是一种近似求解实数方程式的方法。(注:Joseph Raphson在1690年出版的《一般方程分析》中提出了后来被称为“牛顿-拉弗森法”的数学方法,牛顿于1671年写成的著作《流数法》中亦包括了这个方法,但该书在1736年才出版。) ...
5.2 Newton-Raphson method The Newton-Raphson method is one of the most popular and efficient algorithms for finding approximate solutions of a real function. The effectiveness of the Newton-Raphson method is because it does not work on an interval but bases its strategy on an iterative process....
We can find these roots of a simple function such as: f(x) = x2-4 simply by setting the function to zero, and solving: f(x) = x2-4 = 0 (x+2)(x-2) = 0 x = 2 or x = -2 The Newton-Raphson method uses an iterative process to approach one root of a function. The ...
