OK, so last time we saw how to use Lagrange multipliers to find the minimum or maximum of a function of several variables when the variables are not independent.
上次我们看了,怎样利用拉格朗日算子,去求解一个受约束的,多变量函数的最大最小值。
This paper treated discontinuous medium boundary condition by using visual principle and through a more convenient method of Lagrange multipliers method.
本文利用可视原则对不连续介质边界条件等效处理,通过一种更简便的拉格朗日法施加不连续边界以及本质边界条件。
Chapter 13 contains an excellent exposition of the Lagrange multipliers technique.
这本书的第13章对拉格兰兹乘数法有非常精辟的讲解。
