1.m文件編寫
functionb = MyFunc(a)
b = a.*a;
將M文件保存爲matrixp.m，保存在F:/test文件夾中。然後在Matlab主窗口中將當前文件夾改爲F:/test：
2..下面爲matlab的m文件轉換爲dll的操作步驟。
>> mex -setup

Warning: MEX-files generated using Microsoft Visual C++ 2008 require
that Microsoft Visual Studio 2008 run-time libraries be

If you plan to redistribute your MEX-files to other MATLAB
users, be sure that they have the run-time libraries.

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.

>> mcc -W cpplib:libmatrixp -T link:lib matrixp.m -C
3.執行完第二步後，會生成以下九個文件
Matlab編譯後會在Test文件夾下生成9個文件，分別是：
mccEcxludedFiles.log
libmatrixp.cpp
libmatrixp.ctf
libmatrixp.dll
libmatrixp.exp
libmatrixp.exports
libmatrixp.h
libmatrixp.lib
readme.txt
我們需要的一共有四個文件libmatrixp.ctf
libmatrixp.dll
libmatrixp.h
libmatrixp.lib
至此，matlab部分完成，在vs部分見（二）
