（1）该码功能是将数组后n为一次放在数组前面，不改变其他元素顺序； （2）用二分法求方程的根。-(1) of the code after the function is an array on an array of n for the first time in front of the other elements do not change the order (2) equation for the root of the dichotomy.

matlab源程序代码，应用于非线性方程求根等-Roots of nonlinear equations

给定初值及容许误差，利用newton迭代法求方程的根。-Given the initial value and the allowable error, find the root of the equation using newton iteration.
