%    A = SET(A,VARARGIN)

% Sets dataset fields (given as strings in VARARGIN) of the dataset A.
% E.G.: A = SET(A,'data',DATA,'nlab',NLAB).
% This is not different from using the field specific routines
% (e.g. SETDATA(A,DATA)

% PRIOR       prior probabilities
% COST        classification cost matrix
% LABLIST     labels of the classes
% TARGETS     dataset with soft labels or targets
% LABTYPE     label type: 'crisp','soft' or 'target'
