fzero (MATLAB Functions)

8-3 函數的求根. fzero 指令可用於單變數函數的求根，其使用語法如下：. x = fzero ... optimset 通常用於設定最佳化的選項，將在下節中詳細介紹。 MATLAB程式設計：進階篇.

fzero. 找只有一個變數函數零的部份. Syntax. x = fzero(fun,x0) x = fzero(fun,x0,options) x = fzero(fun,x0,options,P1,P2,...) [x,fval] = fzero(.

The fzero command finds a point where the function changes sign. If the function is continuous, this is also a point where the function has a value near zero.

The fzero command is a function file. The algorithm, created by T. Dekker, uses a combination of bisection, secant, and inverse quadratic interpolation methods.

此MATLAB 函数尝试求出fun(x) = 0 的点x。此解是fun(x) 变号的位置- fzero 无法求函数（例如x^2）的根。

此MATLAB 函数尝试求出fun(x) = 0 的点x。此解是fun(x) 变号的位置- fzero 无法求函数（例如x^2）的根。

Root of a Function Defined by a File. Find a zero of the function f(x) = x3 – 2x – 5. First, write a file called f.m . function y = f(x) y = x.^3 - 2*x - 5;.
