使用 mex 时出错:找不到支持的编译器或 SDK

Error using mex: No supported compiler or SDK was found

尽管我通过键入 mex -setup 收到以下消息:

>> mex -setup
MEX configured to use 'Microsoft Visual C++ 2013 Professional (C)' for C language compilation.
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:
     http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html.

To choose a different language, select one from the following:
 mex -setup C++ 
 mex -setup FORTRAN

当我要编译某个.cpp文件时,出现以下错误:

>> mex -g mx_minimum_power.cpp cvm_em64t_debug.lib
Error using mex
No supported compiler or SDK was found. For options, visit 
http://www.mathworks.com/support/compilers/R2015a/win64.html.

编译.cpp文件使用C++编译器(.c文件使用C编译器)。
使用 mex -setup C++,用于设置 C++ 编译器。

显然,使用 mex 指令时,源文件扩展名很重要...
