首先，配置MATLAB
用如下命令：
mex –setup
mbuild -setup
例一：将m文件转化成库文件使用
1、建立一个名为ceshidll.m的M函数文件，该函数的功能是输入两组数完成两组数据的插值拟合,并将结果用图形表示：
ceshidll.m文件内容如下：
function ceshidll(x,y)
a=min(x):0.1:max(x);
b = interp1(x,y,a,''spline'');%一维插值函数
plot(x,y,''*'',a,b);
2、在MATLAB Command中用如下命令编译函数ceshidll.m：
>> mcc -t -W libhg:dlltest -T link:lib -h libmmfile.mlib ceshidll.m
参数说明：
-t 将m文件编译为C\C++代码
-W libhg:dlltest 生成使用C函数图形库的文件，生成的文件名为dlltest
-T link:lib 生成库文件
-h 辅助选项，可以将任何被调用的辅助函数都包含到编译的文件中
libmmfile.mlib连接任何需要的共享函数库
ceshidll.m 被编译的文件名
编译完成后在MATLAB当前目录下会生成以下文件： ceshidll.c、ceshidll.h 、dlltest.c 、dlltest.exports、dlltest.h、dlltest.mlib、dlltest.exp、dlltest.lib、dlltest.dll。其中dlltest.h 、dlltest.lib和dlltest.dll文件是我们需要的。
使用方法：
#include "matlab.h"
#include "dlltest.h"
#pragma comment(lib,"dlltest")
关键代码：
UpdateData(TRUE); //刷新输入数据
double X[100],Y[100];
CString AA,BB,a;
int i=1;
mxArray *A=NULL; //初始化矩阵
mxArray *B=NULL;
AA=m_edit1; //字符串赋值
BB=m_edit2;
.....//将字符转化为数字
mlfEnterNewContext(0, 0); //自动管理内存
dlltestInitialize();
mlfCeshidll(A,B); //调用dll文件中函数
mxDestroyArray(A); //释放矩阵内存
mxDestroyArray(B);
mlfRestorePreviousContext(0, 0);
例二：将m文件 转换成对应的C\C++文件
1、在MATLAB中编写如下函数：
function [x]=gjfcz(A,b)
%A=[-1.5 1 2; 4 2 3 ; -3 2 8]
%b=[3;5;6]
x=A\b
保存名为gjfcz.m，该函数的功能为求解线形方程组，可参考第四章的内容。
2、在MATLAB的命令窗口输入以下命令：
mcc –m gjfcz.m
该命令用来生成对应的C文件和可执行程序。在MATLAB工作目录下(一般是MATLAB\work)将会生成如下文件：gjfcz.exe，gjfcz.c，gjfcz.h，gjfcz_main.c，其中gjfcz.c，gjfcz.h是我们需要的文件。
3、新建名为JXXFC基于对话框的工程，面板上添加一个按扭。
4、拷贝gjfcz.c，gjfcz.h两文件到工程目录下，并将文件引入工程(Project->Add to Project->Files)。
5、为按扭添加如下响应代码：
void CJXXFCDlg::OnButton1()
{
static double Adata[]={-1.5,4,-3,1,2,2,2,3,8};
static double bdata[]={3,5,6};
double Xdata[100];
mxArray *A = NULL;//赋初值
mxArray *b = NULL;
mxArray *x = NULL;
mlfEnterNewContext(0, 0);
//创建矩阵
mlfAssign(&A, mlfDoubleMatrix(3, 3, Adata, NULL));
mlfAssign(&b, mlfDoubleMatrix(3, 1, bdata, NULL));
InitializeModule_gjfcz();
x=mlfGjfcz(A,b);//调用gjfcz.c中的函数求解
TerminateModule_gjfcz();
memcpy(Xdata,mxGetPr(x),3*sizeof(double)); // mxGetPr(x)用来得到x的地址，从而获得matlab输出
CString R;
R.Format("%f\n%f\n%f",Xdata[0],Xdata[1],Xdata[2]);
MessageBox(R);
mxDestroyArray(A);
mxDestroyArray(b);
mxDestroyArray(x);
mlfRestorePreviousContext(0, 0);
}
例三：利用图形库画图
写一个简单的m函数：
function y=huatu_test()
x=-10:0.1:10;
y=sin(x);
plot(x,y,''*'')
文件保存为huatu_test.m。
mcc -t -W libhg:dlltest -T link:lib -h libmmfile.mlib huatu_test.m
#include "dlltest.h"
打开dlltest.h文件，里面有有关函数的定义，找到其中三个函数：
extern mxArray * mlfHuatu_test(void);
extern void dlltestInitialize(void);
extern void dlltestTerminate(void);
从函数意思不难知道它们的作用，dlltestInitialize用来初始化dll库，dlltestTerminate用来结束调用dll,mlfHuatu_test为主程序执行函数。将三个函数拷贝到button响应代码中，进行修改：
void CCeshiDlg::OnButton1()
{
dlltestInitialize();
mlfHuatu_test();
dlltestTerminate();
}
利用mcc命令，通过不同的参数设置可以生成不同的文件，例如：
mcc -B sgl myfun 将myfun.m文件生成对应的c文件和使用c图形库的可执行程序
mcc -B sglcpp myfun 将myfun.m文件生成相应的c++文件和使用c++图形库的可执行程序
mcc的参数实际上有很多，例如：
mcc -t -W main -L C -T link:exe -h libmmfile.mlib myfun
该命令是将myfun.m生成可执行c程序
为了简化选项设置，编译器提供了宏选项，实际上上述命令利用一个参数就可以了：
mcc -m myfun
该命令和上述命令是等价的,也是用来生成可执行c程序。关于mcc命令详细参数设置可以参考MATLAB帮助文档。
大家在使用VC调用MATLAB中遇到什么问题，可以发电子邮件到[email protected],把遇到的问题说清楚，正在写书，同时有什么好的建议，也欢迎发邮件来。
关于程序运行的说明：
1、根据实际情况修改VC中头文件和库文件的路径;
2、如果自己编写的程序图形不能显示菜单栏和工具栏,拷贝文件夹bin到当前目录下
MCC MATLAB to C/C++ Compiler (Version 3.0).
MCC [-options] fun [fun2 ...] [mexfile1 ...] [mlibfile1 ...]
Translate fun.m to fun.c or fun.cpp, and optionally create any supported
binary file. Write any resulting files into the current directory, by
default.
If more than one M-file is specified, a C or C++ file is generated for each
M-file.
If C or object files are specified, they are passed to MEX or MBUILD along
with any generated C files.
If MEX-files are specified, MCC will generate wrapper code so that calls can
be made from compiled M-files to the specified MEX-files. Also, if a
MEX-file and an M-file with the same base name are located in the same
directory, specifying the MEX-file causes MCC to use it instead of the
M-file. Otherwise MCC favors M-files over MEX-files.
MLIB files describe the functions in a shared library created by MCC (see -W
lib below). Specifying an MLIB file tells MCC to link to the MLIB file's
corresponding shared library whenever it needs to use any of the functions
found in that library. The MLIB file and its corresponding shared library
file must be located within the same directory.
If conflicting options are presented to MCC, the rightmost conflicting
option is used.
OPTIONS:
A <option> Specify annotation. The following table shows valid <option>
strings and their effects:
annotation:all (*) - All lines from source M-file appear as comments
in generated output file.
annotation:comments - Comments from source M-file appear as comments in
generated output file.
annotation:none - No text from source M-file appears in generated
output file.
line:on - #line directives appear in generated output file
which map lines in source M-code to lines in
output file.
line:off (*) - No such #line directives are generated.
debugline:on - Run-time error messages report the source file
name and line number where they occurred.
debugline:off (*) - Run-time error messages do not report any
information about the source where they occurred.
(*) indicates default setting.
b Generate an MS Excel compatible formula function for the given list of M-files.
B <filename>[:<arg>[,<arg>]] Specify bundle file. <filename> is a text file containing
Compiler command line options. The Compiler behaves as if the "-B
<filename>" were replaced by the contents of the bundle file. Newlines
appearing in these files are allowed and are treated as whitespace.
The MathWorks provides options files for the following:
ccom Used for building a C COM compatible object on Windows
(requires COM Builder)
cexcel Used for building a C MS Excel Compatable COM object on
Windows (requires MATLAB Excel Builder)
csglcom Used for building C COM compatible object on Windows
using the C Graphics Library (requires COM Builder)
csglexcel Used for building a C MS Excel compatible object on Windows
using the C Graphics Library (requires MATLAB Excel Builder)
csglsharedlib
Used for building a C Graphics Library shared library
cppcom Used for building a C++ COM compatible object on Windows
(requires COM Builder)
cppexcel Used for building a C++ MS Excel Compatiable COM object on
Windows (requires MATLAB Excel Builder)
cppsglcom Used for building C++ COM compatible object on Windows
using the Graphics Library (requires COM Builder)
cppsglexcel
Used for building a C++ MS Excel compatible object on Windows
using the Graphics Library (requires MATLAB Excel Builder)
cpplib Used for building a C++ library
csharedlib
Used for building a C shared library
csglsharedlib
Used for building a C Graphics shared library
pcode Used for building MATLAB P-Code files.
sgl Used for building stand-alone C Graphics applications.
sglcpp Used for building stand-alone C++ Graphics Library
applications.
c C only. Translate M-file to C, but do not produce a MEX-file or
stand-alone application. This is equivalent to "-T codegen" as the
rightmost argument on the command line.
d <directory> Output directory. All generated files will be put in
<directory>.
F list. List the <option>s available in the next form of the command,
together with their current values and a short explanation.
F <option>:<number> Typesetting format options. Assign the value <number> to
the formatting option <option>. See "F list" for <option>s.
f <filename> Use the specified options file when calling MEX or
MBUILD. This allows you to use different ANSI compilers. This
option is a direct pass-through to the MEX or MBUILD script. See
"External Interfaces" for more information.
G Debug only. Simply turn debugging on, so debugging symbol
information is included.
g Debug. Include debugging symbol information. This option also
includes the -A debugline:on switch. This will have an impact on
performance of the generated code. If you wish to have debugging
information, but do not want the performance degradation
associated with the debug line information use: -g -A
debugline:off. This option also includes the -O none switch. That
switch causes all Compiler optimizations to be turned off. If you
wish to have some optimizations on, you may specify them after the
debug switch.
h Compile helper functions. All M-functions called will be compiled into the resulting MEX-file or stand-alone application.
i When generating a library include only entry points mentioned on the
command line in the list of exported symbols.
I <path> Include path. Add <path> to the list of paths to search for
M-files. The MATLAB path is automatically included when running from
MATLAB, but NOT when running from DOS or the Unix shell. See "help
mccsavepath".
L <option> Language. Specifies target language. <option> can be "C" for C, "Cpp" for C++, or "P" for MATLAB P-code.
l Line. Generates code that reports file name and line numbers on run-time errors. (Equivalent to -A debugline:on)
m Macro that generates a C stand-alone application. This is equivalent to
the options "-t -W main -L C -h -T link:exe libmmfile.mlib", which can
be found in the file <MATLAB>/toolbox/compiler/bundles/macro_option_m.
Note: the "-h" means that helper functions will be included.
M "<string>" Pass <string> to the MBUILD or MEX script used to build an
executable. If -M is used multiple times, the rightmost occurrence is
used.
o <outputfilename> Output name. Set the name of the final executable output
(MEX or stand-alone application) to <outputfilename>. A suitable,
possibly platform-dependent, extension is added to <outputfilename>
(e.g., ".exe" for PC stand-alone applications, ".mexsol" for Solaris
MEX-files).
O <optimization> Optimization. There are three possibilities:
<optimization class>:[on|off] - Turns the class on or off
For example: -O fold_scalar_mxarrays:on
list - Lists the available optimization classes.
<optimization level> - Uses a bundle file called
opt_bundle_<level> to determine which optimizations are on or off.
For example "-O all" looks for a bundle file called opt_bundle_all
and uses the switches present. The current optimization levels
are "all" and "none". The default is to have all optimizations
on.
p Macro that generates C++ stand-alone application. This is equivalent to
the options "-t -W main -L Cpp -h -T link:exe libmmfile.mlib", which can
be found in the file <MATLAB>/toolbox/compiler/bundles/macro_option_p.
Note: the "-h" means that helper functions will be included.
S Macro that generates Simulink C-MEX S-Function. This is equivalent to
the options "-t -W simulink -L C -T link:mex libmatlbmx.mlib", which can
be found in the file <MATLAB>/toolbox/compiler/bundles/macro_option_S.
Note: the absence of "-h" means that helper functions will not be
included.
t Translate M code to target language. Translate any M-functions specified on the command line to C or C++ functions. This option is included in all macro options. Omitting it allows the generation of wrapper C/C++ files without generating the C/C++ files corresponding to M-files.
T <option> Specify target phase and type. The following table shows valid <option> strings and their effects:
codegen - translate M-files to C/C++ files and generate a
wrapper file. (This is the default -T setting.)
compile:mex - same as codegen, plus compile C/C++ files to object
form suitable for linking into a Simulink
S-function MEX-file.
compile:mexlibrary - same as codegen, plus compile C/C++ files to object form suitable for linking into an ordinary (non-S-function) MEX-file.
compile:exe - same as codegen, plus compile C/C++ files to object form suitable for linking into a stand-alone executable.
compile:lib - same as codegen, plus compile C/C++ files to object form suitable for linking into a shared library/DLL.
link:mex - same as compile:mex, plus link object files into a Simulink S-function MEX-file.
link:mexlibrary - same as compile:mexlibrary, plus link object files into an ordinary (non S-function) MEX-file.
link:exe - same as compile:exe, plus link object files into a stand-alone executable.
link:lib - same as compile:lib, plus link object files into a shared library/DLL.
u <number> Specify that the number of inputs to a generated Simulink
S-function should be <number>. Valid only if either "-S" or "-W
simulink" option has also been specified.
v Verbose. Show compilation steps.
w list. List the <msg> strings allowed in the next form of the command,
together with the full text of the warning messages to which they
correspond.
w <option>[:<msg>] Warnings. The possible options are "enable", "disable",
and "error". If "enable:<msg>" or "disable:<msg>" is specified, enable
or disable the warning associated with <msg>. If "error:<msg>" is
specified, enable the warning associated with <msg> and treat any
instances of that warning as an error. If the <option> but not ":<msg>"
is specified, the Compiler applies the action to all warning
messages. For backward compatibility with previous Compiler revisions,
"-w" (with no option) is the same as "-w enable".
W <option> Wrapper functions. Specify which type of wrapper file should be generated by the Compiler. <option> can be one of "mex",
"main", "simulink", "lib:<string>","com:<component-name>,<class-name>,<version>", or "none"(default). For the lib wrapper, <string> contains the name of the shared library to build. When generating a "lib" wrapper, MCC also creates an MLIB file describing the functions in the shared library.
x Macro that generates a MEX-file. This is equivalent to the options "-t -W mex -L C -T link:mexlibrary libmatlbmx.mlib", which can be found in the file <MATLAB>/toolbox/compiler/bundles/macro_option_x. Note: the absence of "-h" means that helper functions will not be included.
y <number> Specify that the number of outputs from a generated Simulink
S-function should be <number>. Valid only if either "-S" or
"-W simulink" option has also been specified.
Y <license.dat file> Override default license.dat file with specified
argument.
z <path> Specify the path to use for library and include files.
This option uses the specified path for the Compiler libraries
instead of MATLABROOT.
