function e = end(a,k,n)
%END Last index in an indexing expression for a dataset array.
%   END(A,K,N) is called for indexing expressions involving the dataset A
%   when END is part of the K-th index out of N indices.  For example, the
%   expression A(end-1,:) calls A's END method with END(A,1,2).
