            This tool provides a simple interface to LIBSVM, a library for support vector
machines (
It is very easy to use as
the usage and the way of specifying parameters are the same as that of LIBSVM.

This tool provides  also a simple interface to LIBLINEAR, a library for
large-scale regularized linear classification (
 It is very easy to use as the usage and the way of specifying parameters are
the same as that of LIBLINEAR.

This Toolbox is compatible with the NaN-toolbox!

  - module fixed to work with Scilab 6
  - libsvmread fixed
  - some bugs fixed in the help file examples
 - libsvm_loadmodel and libsvm_savemodel fixed
 - st_deviation renamed to stdev
 - 2nu-SVM added
 - LIBLINEAR is updated to 1.94
 - LIBSVM is updated to 3.20
 - some bugfixes
 - The crossvalidation (libsvm_svmtrain with "-v 5") result is now a
vector with [Cross Validation Accuracy, Positive Cross Validation Accuracy,
Negative Cross Validation Accuracy]
 - Depreated stack-c function were removed
 - new functions libsvm_savemodel and libsvm_loadmodel
 - buxfix for getpath
 - help files fixed for libsvm_linpredict and libsvm_lintrain
 - path operations are replaced by fullfile

 - unit tests for libsvmwrite and libsvmread
 - fix issues 805, 806, 808, 809, 813, 814, 
 - renaming of the following functions:
   *svmtrain > libsvm_svmtrain
   *svmpredict > libsvm_svmpredict
   *train > libsvm_lintrain
   *predict > libsvm_linpredict
   *svmconfmat > libsvm_confmat
   *svmgrid > libsvm_grid
   *svmgridlinear > libsvm_gridlinear
   *svmnormalize > libsvm_normalize

This interface was initially written by Jun-Cheng Chen, Kuan-Jen Peng,
Chih-Yuan Yang and Chih-Huai Cheng from Department of Computer
Science, National Taiwan University. 

It was converted to Scilab 5.3 by Holger Nahrstaedt from TU Berlin.
