function theResult = oct_ncfillvalues

% oct_ncfillvalues -- Create a NetCDF file containing default fill-values.
%  oct_ncfillvalues (no arguments) creates 'oct_ncfillvalues.nc', containing
%   variables with the default NetCDF fill-values.  Use "oct_ncdump" to
%   see the exact NetCDF file structure.  This routine returns a
%   Matlab "struct" of fill-values if an output argument is given.
