2.5 Hermite插值 插值方法 NewtonLagrange与插值的不足 y=f(x),其 NewtonLagrange与插值多项式Pn(x)与Nn(x) 满足插值条件:P(xi)=nn(xi)=f(x)i=0,12.n Newton与 Lagrange插值多项式与y=f(x)在插值节点上有相同 的函数值“过点” 但在插值节点上y=f(x)与y=Pn(x)一般不”相切”, f(xi)≠n(x)光滑性较差 Hermite插值:求与y=f(x)在插值节点X1.n上具有相同函数 值及导数值(甚至高阶导数值)的插值多项式

上一讲我们对于全驻波传输线和行驻波传输线引 进了标准状态和等效长度的概念。在全驻波传输线 中,把短路工作状态作为标准状态;完全类似,在行 驻波状?态中,则把小负载电阻=作为标准状 态,其它状态只是在标准状态?上加一个等效长度z (Note:△可正可负)。当正式写电压、电流场沿线分 ?布时还需考虑一附加相位。 这种阻抗面移动的思想对于微波工程中的其它问题也有很大的启发

This lecture continues our analysis of games with payoff uncertainty. The three main objec- tives are: (1) to illustrate the flexibility of the Harsanyi framework (or our version thereof); (2)to highlight the assumptions implicit in the conventional usage of the framework, and the possible departures; (3) to discuss its potential problems, as well as some solutions to the latter

One of the merits of the notion of sequential equilibrium is the emphasis on out-of- equilibrium beliefs-that is, on beliefs (about past and future play)at information sets that should not be reached if given equilibrium is played. The key insight of extensive-form analysis is that out-of-equilibrium beliefs deter. mine equilibrium behavior. For instance, consider the simple two-stage entry deter- rence game in which potential entrant decides whether to enter a market or stay out, and the incumbent decides whether to fight or acquiesce after the entrant's move

This lecture continues the analysis of normal-form games. We analyze general, non-zeros ames, emphasizing the informalequation Rational Behavior Assumptions about Beliefs= Solution Concepts Before we tackle the new material. let us review what we have learned about zerosum games in light of this \equation\. Rational behavior in the context of normal-form games
