prtPreProcPls   Partial least squares
 
    PLS = prtPreProcPls creates a partial least-squares pre-processing
    object.
 
    PLS = prtPreProcPls('nComponents',N) constructs a
    prtPreProcPLS object PLS with nComponents set to the value N.
 
    A prtPreProcPls object has the following properites:
  
     nComponents    - The number of principle componenets
 
    A prtPreProcPls object also inherits all properties and functions from
    the prtAction class
 
    Example:
 
    dataSet = prtDataGenFeatureSelection;  % Load a data set
    pls = prtPreProcPls;                   % Create a prtPreProcPls Object
                         
    pls = pls.train(dataSet);              % Train
    dataSetNew = pls.run(dataSet);         % Run
 
    % Plot 
    plot(dataSetNew);
