function self = ncrec(theNetcdf, theAutoscaleflag)

% ncrec/ncrec -- Constructor for ncrec class.
%  ncrec(theNetcdf, theAutoscaleflag) allocates a new ncrec
%   object for the current record-variables associated with
%   theNetcdf, a netcdf object.  The result is assigned
%   silently to "ans" if no output argument is given.
