matlab的版本要到2015b才支持vs2015，然而自己電腦上用的matlab2014a，和VS2015社區版，不想重新安裝，需要替換其mexopts文件夾，估計就類似於一個mex的Makefile文件，路徑為R2014a\bin\win64\mexopts。下載之，替換即可。mexopts文件夾的下載地址為 http://pan.baidu.com/s/1o8hR926 ，之后做以下步驟編譯即可。
>> mex -setup
MEX 配置為使用 'Microsoft Visual C++ 2015 Professional (C)' 以進行 C 語言編譯。
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

要選擇不同的語言，請從以下選項中選擇一種命令:
mex -setup C++
mex -setup FORTRAN
