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.

Trying to update options file: C:\Documents and Settings\Administrator\Application Data\MathWorks\MATLAB\R2007a\mexopts.bat

From template: D:\PROGRA~2\MATLAB\R2007a\bin\win32\mexopts\msvc80opts.bat

Done . . . % ok，done！

>> make

>>

%至此彻底完成，

%以下是测试

>>load heart_scale.mat

>>model = svmtrain(heart_scale_label, heart_scale_inst, '-c 1 -g 0.07');

>> [predict_label, accuracy, dec_values] = svmpredict(heart_scale_label, heart_scale_inst, model); %

Accuracy = 86.6667% (234/270) (classification)% done
