一类二次型条件极值的求解

On the Solution to the Condition Limit of a Class Quadratic Form

从拉格朗日乘数法入手,讨论一类二次型的条件极值问题,给出了主要结果,并应用它求解多元函数条件极值问题.

This paper has, from the Lagrange multiplier method, discussed the condition limit of a class quadratic form and brought out the main result, applying which to solve the condition limit of function of several variables.
