Follow-up Comment #3, bug #52285 (project octave):
The problem is around line 646 of dMatrix.cc. If the condition number is zero,
any result is set Inf, except for the (numel() == 1 ) case. What was the
purpose of such an explicit exclusion?
I have a more general question: why a scalar is treated as a full matrix and
not (at least) as a triangular matrix?
