| Newtons-Raphsons方法在Mathematica中易于实现,但在Matlab中似乎有点困难。我不知道是否可以将函数传递给函数以及如何将派生函数用作函数。 newtonRaphson[f_, n_, guess_] := If[n == 0, guess, newtonRaphson[f, n - 1, guess - f[guess]/f\'[guess]]] newtonRaphsonOptimize[f_, n_, guess_] ...
Depending on the starting guess value the Newton Raphson method yields one of the three roots. For example, if we start with value xg = − 0.5 the method yields the root x = − 0.093361 after just 5 iterations. A MATLAB code has been presented below for this choice of the starting ...

An analog of the Newton–Raphson formula, which applies in the case of multiple roots, has been given by Schrder. It is considered that a zero of exact multiplicityis available, then the Newton–Raphson formula is replaced by Schrder's formula. With this modification, the difficulties because...
Observe that the Newton-Raphson method determines the roots of the function. I.e. you need to have a functionf(x)such thatf(x)=0at the desired solution. In this case you can definefas f(x) = Time(x) - t wheretis the desired time. Then by the second fundamental theorem...

For example, to find an ''equilibrium'' solution or a ''periodic orbit'', let F ( x ) = X ( x ) − x , where X ( x ) is the result of time integration of an initial condition x . Newton-Raphson method To find the roots x of a function f ( x ) in one dimension, ...
This feature means that complex roots or polynomial equations can be very readily found numerically in cases where it would be difficult or impossible to find them analytically, e.g. when the degree of the polynomial exceeds four or when the roots are not simple. The methods discussed here ...
