Re: saving sparse variables

[David Bateman]

As of 2.1.53 octave does supply the required hooks. I announced it and
even implemented saving of the galois type in octave-forge/main/comms
as an example. Check the functions load_ascii, save_ascii,
load_binary, save_binary, load_hdf5 and save_hdf5 for details

Regards
D.
