function theResult = gt(self, other)

% gt -- Greater-than operator; redirection operator.
%  gt(self, other) returns the arithmetic greater-than
%   comparison of self with other, for self, an ncatt
%   object, and other, an ncatt, double, or char.
%  gt(self, other) redirects self, an ncatt object,
%   into other, a netcdf or ncvar object.
