Copy one of the programs, for example, engdemo.c , to your current working folder: copyfile(fullfile(matlabroot,... 'extern','examples','eng_mat','engdemo.c'),... '.', 'f'); Build the executable file: mex('-v', '-f', fullfile(matlabroot,... 'bin','engopts.sh'),... 'engdemo.c'); Verify that the build worked by looking i...

libsvm usage

FAQ ===== http://www.csie.ntu.edu.tw/~cjlin/libsvm/faq.html#/Q4:_Training_and_prediction DONWLOAD ======== Just need to download 1 zip file from main page. That's all. http://www.csie.ntu.edu.tw/~cjlin/libsvm/ INSTALL ========== make If you want to use parameter estimation, you need to change the code a bit and do following make clean; make install; DATAFORMAT ============== label  1:feat#1  2:feat#2  3:feat#3      N:feat#N Some available data =============== http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/ Use heart_scale data. It works perfectly for all plot, cv and parameter estimation. 2-class CLASSIFICATION with RBF kernel with 5 fold CV ================================= train (support vectors are generated): ./svm-train -s 0 -t 2   -g  0.03125 -c 0.25   train.dat  train.model train with CV(No support  vectors are shown, just show your score: AUC,F-score) ./svm-train -...
