function theResult = fillval(self, theNewFillValue)

% ncvar/fillval -- Get or set _FillValue of a netcdf variable.
%  fillval(self) returns the value of the _FillValue
%   attribute of self, an ncvar object.
%  fillval(self, theNewFillValue) sets the _FillValue
%   attribute of self, an ncvar object, to theNewFillValue.
%   The type of the fill value is set to the type of the
%   netcdf variable.  The resulting ncatt object is returned.
