matlab的版本要到2015b才支持vs2015，然而自己电脑上用的matlab2014a，和VS2015社区版，不想重新安装，需要替换其mexopts文件夹，估计就类似于一个mex的Makefile文件，路径为R2014a\bin\win64\mexopts。下载之，替换即可。mexopts文件夹的下载地址为 http://pan.baidu.com/s/1o8hR926 ，之后做以下步骤编译即可。

>> mex -setup

MEX 配置为使用 ‘Microsoft Visual C++ 2015 Professional (C)‘ 以进行 C 语言编译。

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:

要选择不同的语言，请从以下选项中选择一种命令:

mex -setup C++

mex -setup FORTRAN

>> mex -setup C++
