MATLAB is very convenient, but sometimes some special applications require us to Matlab M format
Programs in the file are translated into a form of C / C and compile in the C / C compiler.
The text summarizes the general method.
It takes two cases, the first is that the function of the drawing is not involved in your M file; the second
It is necessary to use the drawing function. The following uses examples, respectively:
The first case:
1. Built a M file, the content is:
%%%%%%%%%%%%%%%%%%%%%%
Function Y = fork_1 (n)
y = 0;
For i = 1: N
y = y i;
end
%%%%%%%%%%%%%%%%%%%%%%
After saving, in the command window:
Enter: (format: mcc -t -l cpp -h file name)
MCC -T -L CPP -H fork_1
Then you will find two files for Fork_1.cpp and fork_1.hpp in your working directory.
2. Built a dialog-based MFC application in VC, named TestFork1, add one
Button, and add a button response function, the function content is described in the fifth step. Be formed
Two files are copied to the TestFork1 directory of the VC project.
3. Select: Project ---> Settings, select Input in the drop-down menu, select Input in the VC ---> Settings, optional list.
Add the contents listed in Appendix A in the object / library module, pay attention to the space to pass them open and ignore
Add the content listed in Appendix B in the library; select the property table C / C option, drop down the menu selection general,
Add the contents of the appendix C in the pre-processing program definition, the original content should be retained, and pay attention to the comma
Separate them. Select the precompiled headers option for the drop-down menu, select "Automatic Us
Compensation header, add stdafx.h, determined.
4. Select: Tools ---> Select, Properties page Select "Directory" in include files:
C: / matlab6p5 / extern / incrude
C: / matlab6p5 / extern / include / cpp
Note that according to your MATLAB's installation location, modify the above address accordingly.
Add in Library Files:
C: / matlab6p5 / extern / lib / win32
C: / Matlab6p5 / Extern / LIB / WIN32 / Microsoft / MSVC60
Note that according to your MATLAB's installation location, modify the above address accordingly.
5. Add the following header file to the file where the button response function is located:
......
#include "matlab.hpp"
#include "fork_1.hpp" ......
Function Response Code is:
INT I;
Mwarray n;
N = 5;
n = fork_1 (n);
i = n.extractscalar (1);
CString Str;
Str.Format ("% d", i);
AfxMessageBox (STR);
6. Compile, connect, execute, everything OK! (Note that if you have used many other functions in your program,
MATLAB will generate a corresponding HPP and CPP files for each function, you must copy your work.
Cheng Dynasty)
The second case:
1. Built a M file:
%%%%%%%%%%%%%%%%%%%%%
Function fork_2 ()
X = [1 2 3];
Y = [1 3 1];
Plot (x, y);
%%%%%%%%%%%%%%%%%%%%%
After saving, in the command window:
Enter: (format: MCC -B SGLCPP file name)
MCC -B SGLCPP fork_2
2.
3.
4.
The next step is similar to the precedent, just this will come out for a fork_2_mainhg.cpp, fork_2.exe and
bin folder. When copy_2_mainhg.cpp and fork_2.exe when copying. But need
The bin folder is taken into the VC's engineering directory.
5. Add the following header file to the file where the button response function is located:
......
#include "matlab.hpp"
#include "fork_2.hpp"
......
Function Response Code is:
LibmmfileInitialize ();
Libmwsglminitialize ();
MLFHGInitialize (null, null);
Fork_2 ();
MLFHGWAITFORFIGURESTODIE ();
MLFHGTERMINATE ();
Libmmfiletermic ();
Libmwsglmterminate ();
6. Compile, connect, execute, everything OK! (Note that if you have used many other functions in your program,
MATLAB will generate a corresponding HPP and CPP files for each function, you must copy your work.
Cheng Dynasty. In addition, the three lines of code before and before, but it should be essential, but it should be guaranteed.
During the entire implementation of your program, they are only called once, so they will be the best.
Place the program's initialization function that is called by the program that is called by the program.

"M file transformation into C / C language file" is very simple, but it will encounter a lot of problems through compilation connections in VC.
Even if compiling and connectivity is not guaranteed correctly, sometimes there will be a lot of tricky troubles, in my other article (in the station): "Analyze: Solve the compilation of M-proceration into CPP procedures" Give up
One such example. In that article, although I finally rely on a few tricks, "Xuan Den Road", I got that problem, but
It is still possible to see that this conversion problem is very troublesome.
