本文从现场总线控制系统的发展现状出发，遵循现场总线控制系统标准的体系结构，仍由通用组态软件实现监控管理功能，由现场总线智能仪表实现生产控制功能。但在连接通用组态软件与现场总线智能仪表的信息通道中，采用OPC服务器、OPCActiveX控件取代10驱动程序，实现与Matlba数据共享和互联，无干扰地增加Matlba强大的符号、数值计算、矩阵运算以及图形显示的功能，实施先进控制、优化控制。 -This article from the fieldbus control system development of the current situation, following the standard fieldbus control system architecture, generic configuration software is still realize monitoring and management functions, by the field bus intelligent instruments of production control functions. However, in general configuration software to connect with fieldbus intelligent instrument information channel, the use of OPC server, OPCActiveX controls to replace the 10 drivers, and realize data sharing and Matlba the Internet without interference to increase Matlba powerful symbols, numerical calculation, matrix calculation and graphical display features, the implementation of advanced control, optimal control.

设计一个矩阵相乘的程序，首先从键盘输入两个矩阵a，b的内容，并输出两个矩阵，-use for qiu niu

浮点数基本运算 浮点数的基本运算主要有四则运算、符号处理、大小比较，以及浮点数分柝等。 包含头文件 "fn.hpp" #include "fn.hpp" 浮点数基本运算 浮点数的基本运算中有加、减、乘、除、取负、绝对值、相等比较等。 加减乘除 加、减、乘、除四个运算极为相似，都是需要两个参数，结果当然也是浮点数了。 例子： // 加 减 乘 除 btil::fn::plus::value // f1+f2 的结果 btil::fn::minus::value // f1-f2 的结果 btil::fn::multiplies::value // f1*f2 的结果 btil::fn::divides::value // f1/f2 的结果 plus::value::f_val // f1+f2 的结果的值 struct one { static const double f_val = 1.0 } // 两个浮点数 struct two { static const double f_val = 2.0 } minus::value::f_val == 0.5 取负 取负运算就是取一个浮点数的负数。-float basic operations of the basic operations are four major operations, symbols, sizes, and float-watchman"s rattle so. The first document contains "fn.hpp"# include "fn.hpp" float float basic operations of the basic operations are, plus or minus, riding, except from negative, in absolute terms, a comparison of the same. The a
