Matlab编译器使用mbuild命令可以直接将C/C++源代码编译为独立运行程序，在这些源代码中可以使用Matlab提供的接口来调用Matlab数学库函数。
虽然生成的可执行程序可以脱离Matlab环境运行，但是它需要Matlab C/C++数学库文件或者图形库文件的支持才能运行。但如果C/C++源代码完全是按传统C/C++源代码语法规则编写，没有包含Matlab数学库和图形库的调用，则不仅可以独立与Matlab环境，也不需要那两个库函数的支持。

Warning: The MATLAB C and Fortran API has changed to support MATLAB
variables with more than 2^32-1 elements. In the near future
you will be required to update your code to utilize the new
API. You can find more information about this at:

Building with the -largeArrayDims option enables the new API.

2.转化BoostImage.m文件
mcc -W cpplib:BoostImage -T link:lib BoostImage -d F:zhangyingxieyulinMatlabToC
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。
2.系统环境设置
我的电脑->属性->高级->环境变量->用户变量->PATH中添加路径：D:Program FilesMATLABR2011binwin32，重启生效。
3.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 FilesMATLABR2011binwin32（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 FilesMATLABR2011bexterninclude
(3)在“Library Directions”项目栏，添加：D:Program FilesMATLABR2011bexternlibwin32microsoft
上述环境只需要配置一次。
另参考：
在此暂时先测试了VS2010调用matlab现有函数的功能：
//
#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(" "))){
fprintf(stderr, " Can't start MATLAB engine ");
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 " , ndims) ;
memcpy(dims , mxGetDimensions(X) , ndims * sizeof(int)) ;
for ( i = 0 ; i < ndims ; i ++ ){
printf("dimension %d : %d " , i , dims[i]) ;
}
printf(" ") ;
//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(" ") ;
}
//---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... ") ;
getchar() ;
engSetVisible(ep , false) ;
printf("type RETURN to unhide the MATLAB command window... ") ;
getchar() ;
engSetVisible(ep , true) ;
printf("type RETURN to END this program... ") ;
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;
}
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。
