配置环境：
系统Windows XP，32位。
MATLAB 2011b（安装路径：D:/Program Files/MATLAB/R2011b）
VS2010 英文版（安装路径：D:/Program Files/Microsoft Visual Studio 10.0）
目的：采用由m文件构造动态链接库生成cpp文件，然后在visual studio中调用。
1. MATLAB 环境配置：

2.转化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最好对应end，否则容易出现 Error using mcc的错误。(但我碰到有个m文件仍不能转化成功，不知什么原因）
其中，mcc是Matlab提供的编译命令，对于这一点，Matlab的帮助说明如下：
-W lib:string link:lib其中-W是控制编译之后的封装格式，cpplib，是指编译成C++的lib，cpplib冒号后面是指编译的库的名字，
-T表示目标，link:lib表示要连接到一个库文件的目标，目标的名字是后面的BoostImage，即你写的m函数的名字。
运行完之后，你的目录下面，将会出现以下一些文件：
BoostImage.cpp
BoostImage.exp
BoostImage.dll
BoostImage.exports
BoostImage.h
BoostImage.lib
mccExcludedFiles.log
readme.txt
具体每一个文件的意思，请查帮助，这里只说其中很有用的几个：
BoostImage.dll是编译好的动态库，BoostImage这个函数封装在里面，BoostImage.h是对应的头文件，在C里面调用这个函数的时候，需要include这个头文件在这个头文件的最后，你可以看到下面的内容：
extern LIB_BoostImage_CPP_API void MW_CALL_CONV BoostImage(int nargout, mwArray& output_im, const mwArray& input_im, const mwArray& Mboost);
这就是BoostImage的C函数的声明。nargout表示输出变量的个数，a，b，c就是对应了m函数的几个变量。
注意，a，b，c三个变量的类型是mwArray，这是Matlab提供的一个特殊的变量类型（在7.0的版本，编译之后，变量类型是mxArray）。mwArray是一个类，具体可以查帮助。
4.系统环境配置
我的电脑->属性->高级->环境变量->用户变量->PATH中添加路径：D:\Program Files\MATLAB\R2011b\bin\win32，重启生效。
5.VS2010环境配置
新建一个win32 控制台应用程序，命名为MatlabTest.
右键MatlabTest解决方案->properties->VC++ Derections
(1)在“Executable Directions”项目栏，添加：D:\Program Files\MATLAB\R2011b\bin\win32（注意：当前的Mathlab安装在D:\Program Files下面）
(2)在“include Directions”项目栏，添加：D:\Program Files\MATLAB\R2011b\extern\include
(3)在“Library Directions”项目栏，添加：D:\Program Files\MATLAB\R2011b\extern\lib\win32\microsoft
上述环境只需要配置一次。
在此暂时先测试了VS2010调用matlab现有函数的功能：

运行结果：
若出现如下问题：
error C2371: 'char16_t' : redefinition; different basic types
在混合编程中，也许会出现如下错误：
—————————————————————————————————————————————————
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的定义，而Matlab的matrix.h也包含对char16_t的定义，所以同时包含这两个头文件的话，会导致重复定义char16_t的错误。
解决方案：
参考：http://maciejgryka.com/bits/2011/09/char16_t-conflict-while-mexing-with-vs2010/
完全没有必要修改这两个头文件（以防修改之后，会在将来导致一些问题），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。这就要求我们必须知道所包含的头文件是否包含matrix.h。
