Follow-up Comment #15, bug #47236 (project octave):

@Marco: What about my suggestion in comment #13:

"I think what should happen is a script gets written that does the full
combinatorial test of all matrix types against all solver options ('lm', 'sm',
'sa', 'la' etc.). Run that script on Octave and Matlab and see where the
differences are."

I see that you took my suggestion and made a special exception for "SA".  Are
there other cases that we need to add?  Without a full test it seems like
eventually someone is going to come along and say it doesn't work with option
'li'.  We will fix that in a different bug report.  And then someone will file
a bug that it doesn't work with 'si'.  This will go on and on until we have
eventually tested all options.
