% DESCRIPTION
% By default the feature size of a dataset is its number of features, i.e.
% the number of columns in the DATA field of A. If the features are samples
% of a multi-dimensional data item, e.g. the pixels of an image, the
% original size of this data item may be stored in FEATSIZE. The product of
% all elements in FEATSIZE has to be equal to the number of columns in the
% DATA field of A.
