If ncautonan is called with one argument, it returns the autonan status of the NetCDF variable nv. With two arguments, it sets the autonan status to status. If autonan status is 1, all NaNs in the octave variable to store are replaced by the corresponding value of the _FillValue attribute. This feature is disabled if autonan is 0 (default).
