prtFeatSelStatic/prtFeatSelStatic
  prtFeatSelStatic  Static feature selection object.
 
   FEATSEL = prtFeatSelStatic creates a static feature selection
   object. 
   
   FEATSEL = prtFeatSelStatic('selectedFeatures', FEATURES) creates a
   static feature selection object with the selectedFeatures parameter
   set to FEATURES.
  
   A static feature selction object selects the features specified by
   the selectedFeatures parameter.
 
    Example:
    
    dataSet = prtDataGenIris;            % Load a data set with 4 features
    StaticFeatSel = prtFeatSelStatic; % Create a static feature
                                      % selection object.
    StaticFeatSel.selectedFeatures = [1 3];   % Choose the first and
                                              % third feature
    % Training is not necessary for a static feature selection object,
    % the following command has no effect.
    StaticFeatSel = StaticFeatSel.train(dataSet);  
    
    dataSetReduced = StaticFeatSel.run(dataSet);   %Run the feature
                                                   %selection
    explore(dataSetReduced);
