摘　　要：利用方向导数、梯度及内积、二次型三种方法分别判别函数极值,通过二元函数求极值的方法介绍多元函数极值的求法.This text makes use of a direction to lead a number,steps degree and inside accumulate,two types these three kinds of method distinguishes a function pole value respectively,the method which begs a pole a value through a 2 dollars function introduces diverse function to be worth vevy much of beg a method.

关 键 词：多元函数 极值 方向导数 梯度 内积 二次型 正定矩阵
