Would you like mex to locate installed compilers [y]/n?

的时候输入n

3、此时会列出matlab支持的编译器

[1] Intel C++ 9.1 (with Microsoft Visual C++ 2005 SP1 linker)

[2] Intel Visual Fortran 10.1 (with Microsoft Visual C++ 2005 SP1 linker)

[3] Intel Visual Fortran 9.1 (with Microsoft Visual C++ 2005 SP1 linker)

[4] Lcc-win32 C 2.4.1

[5] Microsoft Visual C++ 6.0

[6] Microsoft Visual C++ .NET 2003

[7] Microsoft Visual C++ 2005 SP1

[8] Microsoft Visual C++ 2008 Express

[9] Microsoft Visual C++ 2008 SP1

[10] Open WATCOM C++

[0] None

选择安装的VC版本(我装的是VS2005)

5、选择完成之后，会要求指定VC的安装目录 The default location for Microsoft Visual C++ 2005 SP1 compilers is C:\Program Files\Microsoft Visual Studio 8, but that directory does not exist on this machine.   Use C:\Program Files\Microsoft Visual Studio 8 anyway [y]/n? 如果安装目录是自动搜索到的目录C:\Program Files\Microsoft Visual Studio 8 anyway，则输入y，否则输入n,然后手动输入VC安装目录
