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...
Newton-Raphson method This method is based on the Newton-Raphson general algorithm for the solution of a set of simultaneous non-linear equations. F(X) = 0, where F is a vector of functions f1 to fn in variables x1, to xn. At each iteration of this method, the non-linear problem is...

This paper presents a two-transformation technique which enables us to make the initial guess unnecessary. Several ...
algebraically, so a numerical method must be used. The Newton-Raphson Method is the easiest and most dependable way to solve equations like this, even though the equation and its derivative seem quite intimidating. Depending on the conditions under which you are attempting to solve this equat...
a method of approximating a rootx0of the equationf(x) = 0; also called the method of tangents. In Newton’s method, the initial (“first”) approximationx=a1is used to find a second, more accurate, approximation by drawing the tangent to the graph ofy=f(x) at the pointA[a1,f(a1...
