%SETFEATSIZE Set the feature size of a dataset%%   A = SETFEATSIZE(A,FEATSIZE)%% INPUT %   A         Dataset%   FEATSIZE  Feature size vector% % OUTPUT%   A         Dataset%% 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.
