模式识别工具箱,本人毕业论文时用到的,希望对大家有用!

%GETFEAT Get feature labels of dataset or mapping
%
%	labels = getfeat(a)
%	labels = getfeat(w)
%
% Returns the labels of the features in the dataset a or the labels
% assigned by the mapping w.
%
% If a (or w) is neither a dataset nor a mapping, a set of dummy
% labels is returned, one for each column in a. All these labels have the
% value 255.
%
% Note that for a mapping w, getfeat(w) is effectively the same as getlab(w).
%
% See datasets, mappings, getlab
