一 spider主页http://www.kyb.mpg.de/bs/people/spider/ （也可以在google上搜索spider matlab得到），关于它的介绍可以参考网址资料
二 使用时为matlab+spider+Weka；因为spider中的一些算法引用了Weka，比如j48
安装注意：
1 matlab7（R14）
6.5版本对java的支持不够，还没有开发javaclasspath等函数
??? Undefined function or variable 'javaclasspath'.
??? Undefined function or variable 'javaaddclasspath'.
2 jre1.4.2
matlab7自带的是1.4.2；matlab6自带的是1.3.可以在D:\MATLAB7\sys\java\jre\win32下看到。如果装了matlab7，使用它自带的1.4.2就可以了，尤其不要使用1.6，因为1.6太新了，matlab还不支持。可以在Matlab下使用 version -java查看JVM版本。
如果你想使用1.5的话，C:\Program Files\Java\jre1.5.0_10；把jre1.5.0_10这个文件夹拷贝到D:\MATLAB7\sys\java\jre\win32下，然后增加环境变量MATLAB_JAVA：D:\MATLAB7\sys\java\jre\win32\jre1.5.0_10。这一步如果有问题的话，重启Matlab会给出错误提示。找不到什么什么文件...
3 Weka3.4.10
使用weka版本低一些即可，高的不行，因为高版本的weka可能是用高版本的jvm支持的。
我使用的组合是 matlab7（R14）+jre1.4.2（matlab7自带的，不需要任何设置）+Weka3.4.10
三 使用方法
1 下载spider，有core和extra两个压缩包，把他们解压到同一个文件夹spider下面，然后放到$matlabroot\toolbox下面
2下载weka3.4.10，找到weka.jar放到$matlabroot\java\jar下面
3 启动Matlab打开$matlabroot\toolbox\spider\use_spider.m运行
提示spider的一些信息和 WEKA support enabled!表示成功了。
然后可以使用 help spider命令查看信息，他的功能列出如附录，然后就可以训练了。
四 一个简单的例子
X=rand(50)-0.5; Y=sign(sum(X,2));
dtrain=data(X,Y);
%生成训练集，也可以使用load()从文件读取
model=train(svm,dtrain));
%使用函数train（）训练模型
rtest=test(dtest,model);
%使用训练好的模型对验证集dtest测试，返回测试结果
