Matlab 2013a 和 VS2010 混合编程

原作者: [db:作者] 来自: [db:来源] 收藏邀请

最近由于项目需求，某项目的算法是基于MATLAB完成的，在短时间内需要去调用算法功能。因此，基于MATLAB生成DLL, C 调用的方式完成。

环境：MATLAB 2013a + VS2010 + win8.1 + 64位系统

一、MATLAB 编译环境设置

1. 安装，MATLAB安装时选择 force 32bit, 这样生成的dll在32位和64位的机器上都可以调用。

2. 装好MATLAB 2013后，打开软件，进行配置

27 users, be sure that they have the run-time libraries.

37 Done . . .

这样，MATLAB的Mex编译环境就配置好了。

二、MATLAB 代码编译dll

打开MATLAB源代码，找到最顶层的m文件，注意顶层必须为function方式。

例如，MATLAB的顶层函数为

文件 ship_track1.m

1 function finish_flag = ship_track1(input_x,input_y,num_ori)

为某目标检测算法，input_x ,input_y,和num_ori为输入的3个参数

那么编译的指令为

1 >> mcc -W cpplib:libship_track1 -T link:lib ship_track1.m -C

配置完成后会在MATLAB工程目录生成7个文件

1 libship_track1.cpp
2 libship_track1.ctf
3 libship_track1.dll
4 libship_track1.exp
5 libship_track1.exports
6 libship_track1.h
7 libship_track1.lib

当然我们需要用到的只有4个

1 libship_track1.ctf
2 libship_track1.dll
3 libship_track1.h
4 libship_track1.lib

三、VS2010 MFC 工程配置

1. 新建VS2010 MFC 工程

2. 将第二步MATLAB编译生成的4个文件拷贝入MFC工程目录下

将头文件 libship_track1.h 添加进工程

3. 项目属性设置

1）选择项目->项目属性->所有配置

C/C++ -> 常规->附加包含目录，找到MATLAB下的include目录

1 D:\Program Files (x86)\MATLAB\R2013a\extern\include

（根据MATLAB的安装路径确定）

2）链接器->常规->附加库目录

1 D:\Program Files (x86)\MATLAB\R2013a\extern\lib\win32\microsoft

3) 链接器->输入->附加依赖项

1 libship_track1.lib
2 libship_track2.lib
3 mclmcrrt.lib
4 libmx.lib
5 libmat.lib
6 mclmcr.lib

到此就配置完成。

四、MFC 调用DLL

1. 初始化

1 if(!libship_track1Initialize())    //初始化1通道
2 {
3       //MessageBox(_T("could not initialize the application"));
4 }

2. 传递参数

 1 double _Data1_1[5] = {0};                //输入数组
 2 double _Data1_2[5] = {0};
 3 for(int i=0; i< chn1_num; i++)
 4 {
 5     _Data1_1[i] = Chan1_x[i];
 6     _Data1_2[i] = Chan1_y[i];
 7 }
 8 
 9 mxArray* Data1_1 = mxCreateDoubleMatrix(1, 5,mxREAL);     //创建1*5矩阵
10 memcpy(mxGetPr(Data1_1), (void*)_Data1_1,sizeof(_Data1_1));           //拷贝输入数据
11 mxArray* Data1_2 = mxCreateDoubleMatrix(1, 5,mxREAL);     //创建1*5矩阵
12 memcpy(mxGetPr(Data1_2), (void*)_Data1_2,sizeof(_Data1_2));           //拷贝输入数据
13 double _Data1_3[1];
14 _Data1_3[0] = chn1_num;
15 mxArray* Data1_3 = mxCreateDoubleMatrix(1, 1,mxREAL);     //创建1*1矩阵;
16 memcpy(mxGetPr(Data1_3), (void*)_Data1_3,sizeof(_Data1_3));           //拷贝输入数据
17 mxArray *input1[3] = {Data1_1,Data1_2,Data1_3};                               //将矩阵x的指针作为输入参数传递进去
18 //mxArray *output[1];                        //定义输出参数指针
19 mlxShip_track1(0,NULL, 3, input1);
