Update of bug #53390 (project octave):
Status: None => Confirmed
_______________________________________________________
Follow-up Comment #1:
Confirmed. I used the following test script (attached).
for i = 1:100
S = sprand (1000, 1000, 1 / 1000);
[L,U] = lu (S);
fprintf (stderr, "%d\n", i);
endfor
Octave rarely gets to more than 3 iterations before lu fails.
(file #43610)
