c++调用matlab函数.doc

问题描述 有关在C++程序中使用MATLAB编译产生的动态链接库DLL MATLAB可以把m代码编译成两种DLL，分别是C语言接口和C++语言接口的DLL。这里以调用C++接口的DLL中的函数为例来介绍。在C++接口的DLL中，函数的输入、输出参数都是mwArray对象。所以问题归结为如何在C++程序中使用mwArray。在这个例子中，输入输出都是矩阵，至于标量，矩阵。 实验内容： 把一个简单的m代码编译成C++接口的DLL，然后在C++程序中调用。为了简单起见，这里的C++程序是一个Win32 Console程序，而不是Windows图形界面的程序，不过不妨碍我们的讨论。 Windows xp 2002 sp3 Matlab 2008b 安装路径：D:\Program Files\MATLAB\R2008b Vs 2008 sp1 安装路径：D:\Program Files\Microsoft Visual Studio 9.0 配置matlab生成dll文件： 在matlab 中选择C++编译器 mbuild -setup Please choose your compiler for building standalone MATLAB applications: Would you like mbuild to locate installed compilers [y]/n? n Select a compiler: [1] Lcc-win32 C 2.4.1 [2] Microsoft Visual C++ 6.0 [3] Microsoft Visual C++ .NET 2003 [4] Microsoft Visual C++ 2005 [5] Microsoft Visual C++ 2005 Express Edition [6] Microsoft Visual C++ 2008 [0] None Compiler: 6 The default location for Microsoft Visual C++ 2008 compilers is C:\Program Files\Microsoft Visual Studio 9.0, but that directory does not exist on this machine.
