多元函数极值的一种新方法

New method of extreme value of function of several variables

通过一元函数求极值的方法 ,介绍了多元函数求极值的一种新方法 ,即利用梯度及内积 。

We introduce a new method of extreme value of functions of several variables by the method of extreme value of functions of a variable.So it can simply calculate the extreme value by gradient and inner product.
