SPIDER The Spider Download
Download the latest version here .Just unzip into the directory of choice. Start MATLAB and run the script "use_spider" to startup.
If you use the Spider allthe time, it would be a good idea to call "use_spider" in your startup.mfile and to add the Spider root directory permanentlyto your MATLAB search path using, for example, PATHTOOL.A provided program "spider_init" attempts to do this but if your startup.mfile is not in the usual place (in the matlab directory) then you haveto do this manually.
Once installed, to get started type "help spider" and "help demos".E.g run spider/demos/microarray/go.m

Want to try something simple to start with on the command-line? Try these:
X=rand(50)-0.5; Y=sign(sum(X,2)); r=train(svm,data(X,Y)) or use toy
and
toy2d
, simple objects for generating toy datasets:
[r a]=train(svm('C=10'),toy2d); plot(a);
loss(train(svm,toy))
loss(train(cv(svm),toy))
get_mean(train(cv(svm),toy))
get_mean(train(cv(chain({l0 svm})),toy))
k=param(knn,'k',1:5); get_mean(train(cv(group({k gridsel(k) svm})),toy))
