Lagrange函数的的两个应用

Two Applications of Lagrange Function

介绍Lagrange函数在大学数学教学中的两个重要应用,利用Lagrange函数中对偶问题来引入特征值和特征向量的定义,以及在规划中由已知原问题求对偶问题.

This paper introduces two applications of Lagrange function,in the process of teaching college mathematics. One application is to introduce the definitions of eigenvalue and eigenvector, and the other one is to solve the dual problem of an optimal problem.
