1 首先我们要下载一个Libsvm 工具箱 其中，这一切都可以被下载到
2 我们解包 我解压在桌面上 住址C:\Users\Administrator\Desktop\libsvm
3打开matlab 导航到的例子，在下列文件夹
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvdTAxMDQxNjEwMQ==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" height="62" width="731">
4 我们依照这个流程输入下面代码
>>
mex -setup
Welcome to mex -setup. This utility will help you set up
a default compiler. For a list of supported compilers, see
http://www.mathworks.com/support/compilers/R2012b/win64.html
Please choose your compiler for building MEX-files:
Would you like mex to locate installed compilers [y]/n?
n
Select a compiler:
[1] Intel C++ 12.0 (with Microsoft Software Development Kit (SDK) linker)
[2] Intel C++ 12.0 (with Microsoft Visual C++ 2008 SP1 linker)
[3] Intel C++ 12.0 (with Microsoft Visual C++ 2010 linker)
[4] Intel C++ 11.1 (with Microsoft Visual C++ 2008 SP1 linker)
[5] Intel Visual Fortran 12 (with Microsoft Software Development Kit (SDK) linker)
[6] Intel Visual Fortran 12.0 (with Microsoft Visual C++ 2008 SP1 linker)
[7] Intel Visual Fortran 12.0 (with Microsoft Visual C++ 2008 Shell linker)
[8] Intel Visual Fortran 12.0 (with Microsoft Visual C++ 2010 linker)
[9] Intel Visual Fortran 11.1 (with Microsoft Visual C++ 2008 SP1 linker)
[10] Intel Visual Fortran 11.1 (with Microsoft Visual C++ 2008 Shell linker)
[11] Microsoft Software Development Kit (SDK) 7.1
[12] Microsoft Visual C++ 2005 SP1
[13] Microsoft Visual C++ 2008 SP1
[14] Microsoft Visual C++ 2010
[0] None
Compiler: 14
Your machine has a Microsoft Visual C++ 2010 compiler located at
D:\VS2010 安装. Do you want to use this compiler [y]/n? y
Please verify your choices:
Compiler: Microsoft Visual C++ 2010
Location: D:\VS2010 安装
Are these correct [y]/n? y
***************************************************************************
Warning: MEX-files generated using Microsoft Visual C++ 2010 require
that Microsoft Visual Studio 2010 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:\Users\Administrator\AppData\Roaming\MathWorks\MATLAB\R2012b\mexopts.bat
From template: C:\PROGRA~1\MATLAB\R2012b\bin\win64\mexopts\msvc100opts.bat
Done . . .
**************************************************************************
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/techdoc/matlab_external/bsflnue-1.html
Building with the -largeArrayDims option enables the new API.

>> make
>> 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)
假设数据集中的数据可以载入出来 即显示如红色所看到的 我们就行觉得完毕了配置
须要注意的是 安装后目录绝对地址尽量不要挪动 不然再次执行的时候有可能会报错...
注：蓝色的部分为我们须要手动输入的代码部分 最后一行红色为终于输出
就是这样 其它能够去看matlab论坛的精品帖子
