vs2010和Matlab R2011b 混合編程的配置

配置環境：

系統Windows XP，32位。

 

MATLAB 2011b（安裝路徑：D:/Program Files/MATLAB/R2011b）

 

VS2010 英文版（安裝路徑：D:/Program Files/Microsoft Visual Studio 10.0）

目的：采用由m文件構造動態鏈接庫生成cpp文件，然后在visual studio中調用。

 

1. MATLAB 環境配置：

Please choose your compiler for building standalone MATLAB applications:
 
Would you like mbuild to locate installed compilers [y]/n? y

（注：若是第一次mbuild -setup，選n，再在給出的的選項中選擇2010 compiler，要注意安裝路徑是否相符）
 
Select a compiler:

2.轉化BoostImage.m文件

 mcc -W cpplib:BoostImage -T link:lib BoostImage -d F:\zhangying\xieyulin\MatlabToC\

注：在此的m文件function最好對應end，否則容易出現 Error using mcc的錯誤。(但我碰到有個m文件仍不能轉化成功，不知什么原因）

其中，mcc是Matlab提供的編譯命令，對於這一點，Matlab的幫助說明如下：
-W lib:string link:lib其中-W是控制編譯之后的封裝格式，cpplib，是指編譯成C++的lib，cpplib冒號后面是指編譯的庫的名字，

-T表示目標，link:lib表示要連接到一個庫文件的目標，目標的名字是后面的BoostImage，即你寫的m函數的名字。
運行完之后，你的目錄下面，將會出現以下一些文件：

BoostImage.cpp
BoostImage.exp
BoostImage.dll
BoostImage.exports
BoostImage.h
BoostImage.lib
mccExcludedFiles.log
readme.txt

具體每一個文件的意思，請查幫助，這里只說其中很有用的幾個：
BoostImage.dll是編譯好的動態庫，BoostImage這個函數封裝在里面，BoostImage.h是對應的頭文件，在C里面調用這個函數的時候，需要include這個頭文件在這個頭文件的最后，你可以看到下面的內容：
extern LIB_BoostImage_CPP_API void MW_CALL_CONV BoostImage(int nargout, mwArray& output_im, const mwArray& input_im, const mwArray& Mboost);

這就是BoostImage的C函數的聲明。nargout表示輸出變量的個數，a，b，c就是對應了m函數的幾個變量。
注意，a，b，c三個變量的類型是mwArray，這是Matlab提供的一個特殊的變量類型（在7.0的版本，編譯之后，變量類型是mxArray）。mwArray是一個類，具體可以查幫助。

4.系統環境配置

我的電腦->屬性->高級->環境變量->用戶變量->PATH中添加路徑：D:\Program Files\MATLAB\R2011b\bin\win32，重啟生效。

5.VS2010環境配置

新建一個win32 控制台應用程序，命名為MatlabTest.

右鍵MatlabTest解決方案->properties->VC++ Derections

(1)在“Executable Directions”項目欄，添加：D:\Program Files\MATLAB\R2011b\bin\win32（注意：當前的Mathlab安裝在D:\Program Files下面）
(2)在“include Directions”項目欄，添加：D:\Program Files\MATLAB\R2011b\extern\include
(3)在“Library Directions”項目欄，添加：D:\Program Files\MATLAB\R2011b\extern\lib\win32\microsoft
上述環境只需要配置一次。

在此暫時先測試了VS2010調用matlab現有函數的功能：

 

// MatlabTest.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <stdlib.h>   
#include <stdio.h>   
#include <string.h>   
#include "engine.h"   
#include "matrix.h"   
#pragma comment(lib,"libeng.lib")    
#pragma comment(lib,"libmx.lib")   
int main()  
{  
    Engine *ep;  
    int i , j ;  
    //show how to open MATLAB engine   
    //for remote ones:   
    //engOpen( ADDRESS OF REMOTE SYSTEM ) ;   
    if (!(ep = engOpen("\0"))){  
        fprintf(stderr, "\nCan't start MATLAB engine\n");  
        return EXIT_FAILURE;  
    }  
    //show how to create matrix   
    mxArray *Y = mxCreateDoubleMatrix(1 , 3 , mxREAL) ;  
      
    //show how to put data in matrix   
    double tmp[3] = {1.0 , 2.0 , 3.0} ;  
    memcpy(mxGetPr(Y) , tmp , sizeof(tmp)) ;  
    //show how to put variables in the Engine   
    engPutVariable(ep , "Y" , Y) ;  
    //show how to execute commands in MATLAB   
    engEvalString(ep, "X = ones(5,1) * Y");  
      
    //show how to get variables from the Engine   
    mxArray *X = engGetVariable(ep , "X") ;  
      
    //show how to manipulate dimensions   
    int dims[10] ;  
    int ndims ;  
    ndims = mxGetNumberOfDimensions(X) ;  
    printf("total number of dimensions is %d\n" , ndims) ;  
    memcpy(dims , mxGetDimensions(X) , ndims * sizeof(int)) ;  
    for ( i = 0 ; i < ndims ; i ++ ){  
        printf("dimension %d : %d\n" , i , dims[i]) ;  
    }  
    printf("\n") ;  
    //show how the data is stored in the memory   
    double *p = (double*)mxGetData(X) ;      
    for ( i = 0 ; i < dims[0] ; i ++ ){  
        for ( j = 0 ; j < dims[1] ; j ++ ){  
            printf("%8.2f" , p[j * dims[0] + i]) ;  
        }  
        printf("\n") ;  
    }  
    //---important, to release resources   
    mxDestroyArray(X) ;  
    mxDestroyArray(Y) ;  
    //show how to hide and unhide MATLAB command window   
    printf("type RETURN to hide the MATLAB command window...\n") ;  
    getchar() ;  
    engSetVisible(ep , false) ;  
    printf("type RETURN to unhide the MATLAB command window...\n") ;  
    getchar() ;  
    engSetVisible(ep , true) ;  
    printf("type RETURN to END this program...\n") ;  
    getchar() ;      
    //remembering to close it is important .   
    //but if you are debugging your programs ,    
    //annotate the following line will save you a lot of time ,   
    //for you needn't to restart the Engine .   
    engClose(ep) ;  
      
    //when your work is accomplished , type "exit" in MATLAB command window   
    return EXIT_SUCCESS;  
}  

 

運行結果：

 

若出現如下問題：

 error C2371: 'char16_t' : redefinition; different basic types   

在混合編程中，也許會出現如下錯誤：

 —————————————————————————————————————————————————

C:Microsoft Visual Studio 10.0VCINCLUDEyvals.h(576) : error C2371: 'char16_t' : redefinition; different basic types
C:Matlabr2010aexternincludematrix.h(330) : see declaration of 'char16_t'

 —————————————————————————————————————————————————

原因是VS2010中的yvals.h添加了char16_t的定義，而Matlab的matrix.h也包含對char16_t的定義，所以同時包含這兩個頭文件的話，會導致重復定義char16_t的錯誤。

解決方案：

參考：http://maciejgryka.com/bits/2011/09/char16_t-conflict-while-mexing-with-vs2010/
完全沒有必要修改這兩個頭文件（以防修改之后，會在將來導致一些問題），只需要在包含matrix.h之前包含yvals.h即可。例如：

#include <yvals.h>
#if (_MSC_VER >= 1600)
#define __STDC_UTF_16__
#endif
#include "mex.h"

注：mex.h 包含matrix.h。這就要求我們必須知道所包含的頭文件是否包含matrix.h。
