be-accomplished-in-MatlabaC-CPP-
本书主要介绍如何运用Matlah与C.C + +进行混合程序设计。共分8章。主要包括Matlab程序设计初步、Matlab编译器、Matlab与C语言的接口、生成可独立运行的iatlah程序、VC++调用Matlah程序、Matlab DotNet Builder与VC++,Matcom与C/C++以及VC++调用Matlab C++数学库。另外,附录中介绍有关动态链接库的基础知识。各章包含大量
的实例程序,可供寻求将Matlab程序脱离Matlab环境的Matlab程序设计人员、寻求在Matlab中调用C/C++程序的程序设计人员、寻求在C,C++中调用Matlab程序的程序设计人员学习和参考。(This book describes how to use Matlah mixed with the CC++ programming. Divided into 8 chapters. Including Matlab programming initially, Matlab compiler, Matlab and C language interface to generate can be run independently of the iatlah program, VC++ calls Matlah program, Matlab DotNet Builder and VC++, Matcom and C/C++ and VC++ calling Matlab C++ math library. In addition, the appendix describes the dynamic link library on the basis of knowledge. Each chapter contains a large number of example programs are available for the Matlab program from the Matlab environment, Matlab programmer, seeking to Matlab to call C/C++ program programmers seek to C, C++ calling Matlab program programmers study and reference.)

实验:
有两个个矩阵a和b,均为2行3列。 重载运算符“+”,
(1)使之能用于矩阵的相加。如c=a+b。
(2)如果参与运算的两个操作数中一个是整数即矩阵+3或3+矩阵形式,进行加法运算也能得出和。
(3)定义自减运算符的前置(i++)和后置(++i)重载编写相应程序并验证它的正确性。
