从c++调用MATLAB错误:无法解析的外部符号

从c++调用MATLAB函数时，我遇到了几个错误。主要思路是:首先编译MATLAB函数并生成DLL文件，然后在c++中包含。h和。lib文件。最后，编写.cpp来测试和调用该函数。这是我的详细步骤，请告诉我哪里错了。

(使用MATLAB 2012b和Visual c++ 2008, Windows 7 64位)

:

1. mbuild -setup和mex -setup设置Visual Microsoft Visual c++ 2008 SP1为编译器。

2. 在文件夹C:UsersWangYudongDocumentsMATLABMyAdd_M中创建MyAdd.m，功能如下:

   function [c] = MyAdd(a, b)
   c = a + b;
   

3. mcc -W cpplib:libMyAdd -T link:lib MyAdd编译MyAdd.m，生成libMyAdd.dll、libMyAdd.h、libMyAdd.lib等多个文件。

1. 选择 vc++ Directories→Include files添加E:MATLABR2012bexterninclude .

2. 选择 vc++ Directories→Library files添加E:MATLABR2012bexternlibwin64microsoft和C:UsersWangYudongDocumentsMATLABMyAdd_M .

3. 选择 linkker →Input→Additional Dependencies添加新条目:

   mclmcr.lib
   mclmcrrt.lib
   libmx.lib
   libmat.lib
   libMyAdd.lib
   

4. 新建MyAdd_test.cpp，并将libMyAdd.dll, libMyAdd.h和libMyAdd.lib放在同一个文件夹中。在头文件中增加libMyAdd.h，在资源文件中增加libMyAdd.h和libMyAdd.lib。

MyAdd_test.cpp的代码如下:

#include "mclmcr.h"
#include "matrix.h"
#include "mclcppclass.h"
#include "libMyAdd.h"
int main() {   
    double a = 6;
    double b = 9;
    double c;
    // initialize lib
    if( !libMyAddInitialize()) {
        std::cout << "Could not initialize libMyAdd!" << std::endl;
        return -1;
    }
    // allocate space
    mwArray mwA(1, 1, mxDOUBLE_CLASS);
    mwArray mwB(1, 1, mxDOUBLE_CLASS);
    mwArray mwC(1, 1, mxDOUBLE_CLASS);  
    // set data
    mwA.SetData(&a, 1);
    mwB.SetData(&b, 1);
    // use function: MyAdd
    MyAdd(1, mwC, mwA, mwB);
    // get data
    c = mwC.Get(1, 1);
    printf("c is %fn", c); 
    // terminate the lib
    libMyAddTerminate();   
    // terminate MCR
    mclTerminateApplication();
    return 0;
}  

最后，结果是

MyAdd_test.cpp

实际上，上面的工作是我从c++调用自定义MATLAB函数的测试。我接下来的工作是将一个MATLAB程序转换成c++，其中包含imread, edge, strel等图像处理功能。我试过MATLAB编码器，但它不能转换MATLAB函数。所以我尝试了上面的方法。是转换这些函数的有效方法还是我应该使用OpenCV实现它们?
