function theResult = addoffset(self, theNewAddoffset)

% ncvar/addoffset -- "add_offset" attribute value.
%  addoffset(self) returns the "add_offset" attribute
%   value of self, an "ncvar" object, or 0 if no such
%   attribute exists.
%  addoffset(self, theNewAddoffset) changes the add-offset
%   of self, an "ncvar" object, to theNewAddoffset.
