在VC6.0下面如何调用matlab的程序

软件环境：windows Xp，VC6.0， Matlab 2010b

1、编写测试m函数，这个不变，即如下：

function [y,z] = myadd2(a, b)
% dummy function, just to demonstrate the idea
y = a+b;
z = a+2*b;
end

2、运行mbuild -setup设置好编译器后（我选的是vc6.0的编译器，没用MATLAB自带的），利用

mcc -W cpplib:libmyadd2 -T link:lib myadd2.m -C

生成需要的libmyadd2.dll，libmyadd2.h，libmyadd2.lib，libmyadd2.ctf文件。（注意，R2010b下，mcc -W cpplib:libmyadd2 -T link:lib myadd2.m不再生成libmyadd2.ctf文件，需加-C选项）

3、VC下新建控制台程序，步骤如下：file>new,选择Win32 Console Application，右侧project name 填写

testmyadd2_r2010b

，点击OK。在下一个界面选“a simple application”finish点OK。至此程序框架搭好,将libmyadd2.dll，libmyadd2.h，libmyadd2.lib和libmyadd2.ctf复制到testmyadd2_r2010b工程目录下。

并将libmyadd2.h添加到Header files组内。

4、进行项目必要的设置(注意这里和VC2005有较大不同)。vc主界面进入project>Settings，点C/C++选项卡，Category选择Preprocessor,Additional  include directories下填入如下路径

F:\MATLAB\R2010b\extern\include

(注意2010b下该路径和之前也有不同)。
点“link”选项卡，Category选择General，在下面的Object/library modules 那栏的最后添

libmyadd2.lib mclmcrrt.lib

两个库之间以及和其他库以空格隔开。然后Category选择input，Additional  library path下填写：

F:\MATLAB\R2010b\extern\lib\win32\microsoft

，点击OK。至此配置完毕。

5、打开testmyadd2_r2010b.cpp文件，在#include "stdafx.h"后添加

1. #include <iostream>
   
2. #include "libmyadd2.h"

(注意这里不再需要include  "mclmcr.h"和"mclcppclass.h"了，因为2010b生成的"libmyadd2.h"已经包含这两个头文件了)。之后在main函数里这句上面添加如下代码：

std::cout << "Hello world!" << std::endl;
        /* Initialize the MCR */ 
        if( !mclInitializeApplication(NULL,0) ) 
        { 
                std::cout << "Could not initialize the application!" << std::endl;
                return -1; 
        } 

        // initialize lib
        if( !libmyadd2Initialize())
        {
                std::cout << "Could not initialize libmyadd2!" << std::endl;
                return -1; 
        }

        try
        {
        // declare and initialize a
        mwArray a(2, 2,  mxDOUBLE_CLASS);
        double *aData;
        aData = new double[4];
        int i;
        for( i=0; i<4; ++i)
        {
                aData[i] = 1.0*i;
        }
        // print output
        std::cout << "a = " << std::endl;
        std::cout << aData[0] << ",\t" << aData[1] << std::endl;
        std::cout << aData[2] << ",\t" << aData[3] << std::endl;

        a.SetData(aData, 4);

        // declare and initialize b
        mwArray b(2, 2,  mxDOUBLE_CLASS);
        b(1,1) = 11.;
        b(1,2) = 12.;
        b(2,1) = 21.;
        b(2,2) = 22.;

        mwArray y(2, 2,  mxDOUBLE_CLASS);
        mwArray z(2, 2,  mxDOUBLE_CLASS);

        // call the function
                myadd2(2, y, z, a, b);

        // copy data from mwArray to C++ objects

        // allocate outputs
        double *yData, *zData;
        yData = new double[4];
        if( yData == NULL )
        {
                std::cout << "Failed to allocate memory for yData!" << std::endl;
                return -1;
        }

        zData = new double[4];
        if( zData == NULL )
        {
                std::cout << "Failed to allocate memory for zData!" << std::endl;
                return -1;
        }

        // copy data from mwArray to C++
        y.GetData(yData, 4);
        z.GetData(zData, 4);

        // print output
        std::cout << "y = " << std::endl;
        std::cout << yData[0] << ",\t" << yData[1] << std::endl;
        std::cout << yData[2] << ",\t" << yData[3] << std::endl;

        std::cout << "z = " << std::endl;
        std::cout << zData[0] << ",\t" << zData[1] << std::endl;
        std::cout << zData[2] << ",\t" << zData[3] << std::endl;

        
        // deallocate memory
        delete [] aData;
        delete [] zData;
        delete [] yData;
        }
        catch( const mwException& e)
        {
          std::cerr << e.what() << std::endl;
                  
        }
        // terminate the lib
        libmyadd2Terminate();

        // terminate MCR
        mclTerminateApplication();

然后就ok了

6，里面最绕的莫过于mwArray
可以用下面的代码详细理解mwArray和一般数组之间的区别

        mwArray a(3, 2,  mxDOUBLE_CLASS);  
        double *aData;  
        aData = new double[6];  
        int iii;  
        for( iii=0; iii<6; ++iii)  
        {  
                aData[iii] = iii+1;  
        }  
        // print output  
        std::cout << "a = " << std::endl;  
        std::cout << aData[0] << ",\t" << aData[1] << std::endl;  
        std::cout << aData[2] << ",\t" << aData[3] << std::endl;
        std::cout << aData[4] << ",\t" << aData[5] << std::endl;  
 
        a.SetData(aData, 6);  
        std::cout << "a(1,1)="<<a(1,1)<<std::endl;
        std::cout << "a(1,2)="<<a(1,2)<<std::endl;
        std::cout << "a(2,1)="<<a(2,1)<<std::endl;
        std::cout << "a(2,2)="<<a(2,2)<<std::endl;
        std::cout << "a(3,1)="<<a(3,1)<<std::endl;
        std::cout << "a(3,2)="<<a(3,2)<<std::endl;

运行结果如图：【一位数组到多维数组的组织方式是列优先的】

a =
1,      2
3,      4
5,      6
a(1,1)=1
a(1,2)=4
a(2,1)=2
a(2,2)=5
a(3,1)=3
a(3,2)=6
