Follow-up Comment #9, bug #47415 (project octave):
My last two posts don't show up correctly in the tracker
so I'm trying to post them again.
Octave 4.1
[l, u, p] = lu (A);
issparse (p)
ans = 0
issparse (-p)
ans = 0
-verbaitim-
Matlab
[l, u, p] = lu (A);
issparse (-p)
ans =
1
issparse (p)
ans =
1
-verbaitim-
In Octave 3.8.1 I get:
octave:4> A = sprandn (10, 10, .4);
octave:5> [l, u, p] = lu (A);
octave:6> issparse (p)
ans = 0
octave:7> issparse (-p)
ans = 1
octave:8> version
ans = 3.8.1
this latter seems the most correct to me ...
is there a reason why it was changed?
