以下是步骤： >> mex -setup % 这是必须的 Please choose your compiler for building external interface (MEX) files: Would you like mex to locate installed compilers [y]/n? n %这次是选择编译器，输入n，因为你的是自定义的 %出现下面的选项： Select a compiler: [1] Borland C++ Compiler (free command line tools) 5.5 [2] Borland C++Builder 6.0 [3] Borland C++Builder 5.0 [4] Compaq Visual Fortran 6.1 [5] Compaq Visual Fortran 6.6 [6] Intel C++ 9.1 (with Microsoft Visual C++ 2005 linker) [7] Intel Visual Fortran 9.1 (with Microsoft Visual C++ 2005 linker) [8] Intel Visual Fortran 9.0 (with Microsoft Visual C++ 2005 linker) [9] Intel Visual Fortran 9.0 (with Microsoft Visual C++ .NET 2003 linker) [10] Lcc-win32 C 2.4.1 [11] Microsoft Visual C++ 6.0 [12] Microsoft Visual C++ .NET 2003 [13] Microsoft Visual C++ 2005 [14] Microsoft Visual C++ 2005 Express Edition [15] Open WATCOM C++ 1.3 [0] None Compiler: 13%这次选择13，或许你也可以用其他的 The default location for Microsoft Visual C++ 2005 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? n %这次它说要使用默认的路径 继续选择n Please enter the location of your compiler: [C:\Program Files\Microsoft Visual Studio 8] %它的意思是让你输入编译器的位置，输入：D:\Program Files\Microsoft Visual Studio 8 % 下面就是确认了 Please verify your choices: Compiler: Microsoft Visual C++ 2005 Location: D:\Program Files\Microsoft Visual Studio 8 Are these correct?([y]/n): y *************************************************************************** Warning: MEX-files generated using Microsoft Visual C++ 2005 require that Microsoft Visual Studio 2005 run-time libraries be available on the computer they are run on. If you plan to redistribute your MEX-files to other MATLAB users, be sure that they have the run-time libraries.
