Yes, I was thinking about that too.   I'm guessing that out
of core solvers take a long time to complete, so it is not
something that exists in the domain of exploratory analysis
that octave specializes in.  This is a situation in which a
specialized solver as a separate application driven from
data files is in order.  Sure you can use octave to set up
the files and read the results, but I don't see any point in
embedding the code in octave.
