vs2008调用matlab dll

实验环境：

xp sp3

MATLAB 2009b（安装路径：D:\Program Files\MATLAB\R2009a）

VS2008 中文版（安装路径：D:\Program Files\Microsoft Visual Studio 9.0）

1：在matlab中选择compiler。

在命令行窗口输入：mex -setup

 mex -setup
Please choose your compiler for building external interface (MEX) files:
 
Would you like mex to locate installed compilers [y]/n? n
 
Select a compiler:
[1] Intel C++ 9.1 (with Microsoft Visual C++ 2005 SP1 linker)
[2] Intel Visual Fortran 10.1 (with Microsoft Visual C++ 2005 SP1 linker)
[3] Intel Visual Fortran 9.1 (with Microsoft Visual C++ 2005 SP1 linker)
[4] Lcc-win32 C 2.4.1
[5] Microsoft Visual C++ 6.0
[6] Microsoft Visual C++ .NET 2003
[7] Microsoft Visual C++ 2005 SP1
[8] Microsoft Visual C++ 2008 Express
[9] Microsoft Visual C++ 2008 SP1
[10] Open WATCOM C++
 
[0] None
 
Compiler: 9
 
The default location for Microsoft Visual C++ 2008 SP1 compilers is C:\Program Files\Microsoft Visual Studio 9.0,
but that directory does not exist on this machine. 
 
Use C:\Program Files\Microsoft Visual Studio 9.0 anyway [y]/n? n
Please enter the location of your compiler: [C:\Program Files\Microsoft Visual Studio 9.0] D:\Program Files\Microsoft Visual Studio 9.0
 
Please verify your choices:
 
Compiler: Microsoft Visual C++ 2008 SP1 
Location: D:\Program Files\Microsoft Visual Studio 9.0
 
Are these correct [y]/n? y

2：选择builder

在命令行窗口输入：mbuilder -setup

与上述步骤类似，最后输出：

Done . . .

3:将test1.m文件编译生成所需的 .dll .lib .h文件 

%/*********************** test1.m *************************/
function output = test1(input)
%%
%
%%
output=input.^0.5;
plot(input,output);
axis equal;
return
end

输入：mcc -W cpplib:test1dll -T link:lib test1.m 

生成文件如下:

 

4.新建win32控制台程序，并配置

新建一个win32 控制台应用程序，我取的名字是CallMatDll.当然新建其他的项目类型也可以，我这只是个例子。接下来进行配置，在该项目的属性中进行了配置，只对该项目有效。若建新的项目需要重新配置。项目建好后将test1dll.lib, test1dll.h, test1dll.dll 拷贝到项目目录下。

配置项目属性页/配置属性/C-C++/常规/附加包含目录:

配置项目属性页/配置属性/链接器/常规/附加库目录:

配置项目属性页/配置属性/链接器/输入/附加依赖性，填入test1dll.lib mclmcrrt.lib mclmcr.lib

5.主程序,调试运行

 

#include "mclmcrrt.h"
#include "mclcppclass.h"
#include <iostream>
#include "test1dll.h"
using namespace std;

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

    
    // initialize lib
    if( !test1dllInitialize())
    {
            cout << "Could not initialize libmyadd2!" << endl;
            return -1; 
    }

    // declare and initialize a
    mwArray a(1, 4,  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] <<",\t"<< aData[2] << ",\t" << aData[3] << std::endl;


    a.SetData(aData, 4);

  
    mwArray y(1, 4,  mxDOUBLE_CLASS);
    // call the function
    test1(1, y, a);
    

    // copy data from mwArray to C++ objects

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

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

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

  
    
    // deallocate memory
    delete [] aData;
    delete [] yData;

    /* Block on open figures */
    mclWaitForFiguresToDie(NULL);
   
    // terminate the lib
    test1dllTerminate();
    

    // terminate MCR
    mclTerminateApplication();


    return 0;
}

 

编译运行结果如下：
