This seems to be another symptom of the same permutation matrix bug fixed in this changeset:

http://hg.savannah.gnu.org/hgweb/octave/rev/b646413c3d0e

I'm therefore closing this bug report, as it's not present anymore after that cset.

When using luinc(A,1e-3) the P and Q are supposed to be matrix form as when using lu(A).

This is not the case, I get P and Q as vectors instead which should be the case if I use luinc(A,1e-3,'vector')

I need both P and Q because just L and U will not give the correct result when used.

Example matrices where this happens can be seen in file attached.
