function theResult = dim(self, theDimname)

% netcdf/dim -- Dimensions of a netcdf object.
%  dim(self, 'theDimname') returns the ncdim object
%   whose name is theDimname, associated with self,
%   a netcdf object.
%  dim(self) returns the cell-list of ncdim objects
%   associated with self, a netcdf object.
