% ncrecget -- Emulator for broken mexcdf('recput', ...).
%  status = ncrecput(ncid, recnum, data, autoscale) writes
%   the record whose record number is recnum, to the netcdf
%   file whose id is ncid.  The data are expected to be
%   a single row-vector.  If autoscale is non-zero, then
%   the autoscale facility will be invoked.  if recdim is
%   provided, it substitutes for the actual recdim in the
%   file, if any.
