function [theSrc, theDst] = subs(self, theSrcsubs, theDstsubs)

% ncvar/subs -- Manipulate origin.
%  [{theSrcsubs}, {theDstsubs}] = subs(self) returns the "src"
%   and "dst" subscripts of self, a composite "ncvar" object.
%  subs(self, {theSrcsubs}, {theDstsubs}) sets the "src" and
%   "dst" subscripts of self to the given structs.
