%SETLABELS Reset labels of dataset%%   A = SETLABELS(A,LABELS,J)%% The labels of the dataset A are reset by LABELS. If supplied, the% index vector J defines the objects for wich LABELS applies. If in% LABELS just a single label is given all the objects defined by J% are given that label. If LABELS is empty ([]) or NaN all the objects% defined by J are marked as unlabeled.%% If A has soft labels (label type is 'soft') or has no labels but% targets (label type is 'targets'), these soft labels or targets are% replaced by LABELS, provided it has the right size.%% For soft labels and targets LABELS may be a dataset of which the% data are used for the values of the soft labels or targets and the % feature labels are used to set LABLIST of A.
