Description
给定一个有N个矩阵的矩阵链A1A2A3...An，矩Ai的维数为pi-1*pi。我们都知道，使用朴素的矩阵乘法去乘两个维数分别为x,y和y,z的矩阵，所需要的乘法次数为x*y*z。矩阵链乘法问题就是如何对矩阵乘积加括号，使得它们的乘法次数达到最少。
Input
输入的第一行为一个正整数N(1

一般使用PC Based Controller 都是当作现场设备的一种，也就是要接受
主系统的命令，做一些操作控制。以Modbus 来看属于Slave 的角色，随
时等待接收Modbus Master 的Query Message，然后依据内容做控制，最后
将控制结果以Response Message 回传。本章将以ICP 7524 及ICP 7188E5 等
两种设备分别设计Modbus RTU、ASCII 及Modbus/TCP 的Slave 应用程序，
读者可以将此两种程序的架构再延伸设计至各种实际应用程序。-Generally used as a PC Based Controller is a field device, which is the main system to accept orders, make a number of operational control. Modbus is a look at the role of Slave, Modbus Master at any time waiting to receive the Query Message, and then to do based on the contents of control, the final results will be controlled in order to return the Response Message. This chapter will be ICP 7524 and ICP 7188E5 equipment design, such as two Modbus RTU, ASCII and Modbus/TCP the Slave application, readers can use this framework for the two procedures designed to further extend the range of practical applications.

SQLiteTable3
SQLite Table3.pas修正版，解决中文显示乱码，以及最后一字符乱码。delphi 里UTF8Encode和UTF8Decode两函数配合使用，例：获取sltb := slDb.GetTable(UTF8Encode(sSQL)); 显示字段sd.Cells[i + 1, sltb.Row + 1] :=UTF8Decode(sltb.FieldAsString(sltb.FieldIndex[sltb.Columns[i]]));(The revised version of SQLite Table 3. PAS solves the problem of Chinese display scrambling and last character scrambling. In delphi, UTF8Encode and UTF8Decode functions are used together, for example: get sltb: = slDb. GetTable (UTF8Encode (sSQL); display field sd. Cells [i + 1, sltb. Row + 1]: = UTF8Decode (sltb. Field String (sltb. Field Index [sltb. Columns [i]);)

大气湍流
说明： 在多层共轭自适应光学中，采用相位屏模拟湍流的大气，用以研究湍流大气的最佳分层，确定层边界位置。文中提出了湍流大气的实验室相位屏模拟原理及相位屏个数与边界确定的仿真算法。仿真结果表明。可使用较少的相位屏模拟多层大气湍流，从而使系统结构简化。(In the multi-layer conjugate adaptive optics, the phase screen is used to simulate the turbulent atmosphere, so as to study the optimal stratification of the turbulent atmosphere and determine the boundary position of the layer. In this paper, the principle of phase screen simulation in turbulent atmosphere and the simulation algorithm of the number and boundary of phase screens are proposed. The simulation results show that. A few phase screens can be used to simulate multi-layer atmospheric turbulence, thus simplifying the system structure.)
