[Octave-bug-tracker] [bug #53390] lu factorization of large sparse matrices often fails

[Marco Caliari]

Update of bug #53390 (project octave):

                  Status:               Need Info => In Progress

Follow-up Comment #9:

I made few tests and Option 3) in comment #8 seems to work (in particular,
opts.type="ilutp", opts.droptol=0, opts.thresh=1). I can prepare a file
__lu__.cc which is a simplified version of __ilu__.cc in which only the ilutp
variant is kept (and forced to continue even if the pivot is zero). How to
integrate this into sparse-lu.cc is beyond my possibilities and I need help.
