多元函数的累次极值

SEVERAL TIMES EXTREMUM OF A FUNCTION OF SAVERAL VARIABLES

本文将多元函数极值较化为一元函数极值来处理．从而为三元及三元以上函数极值的判定和计算提供一种方法。

This paper studies extremum of function of several variables by using the extremum of function of one varicble. Thus, it provides a test and an algorithm for extremum of function of three or more variables.
