1.libsvm    http://pan.baidu.com/s/1nu8FvSH

安装参考以上网址

2.测试代码

libsvm的heart_scale.mat数据集下载地址http://pan.baidu.com/s/1jH6JA8u

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

optimization finished, #iter = 134
nu = 0.433785
obj = -101.855060, rho = 0.426412
nSV = 130, nBSV = 107
Total nSV = 130
>> [predict_label, accuracy, dec_values] = svmpredict(heart_scale_label, heart_scale_inst, model);
Accuracy = 86.6667% (234/270) (classification)
