In ilu.m there is a xtest. Matlab is claimed to pass, which is true, but its
result has L singular. Incomplete lu is used for preconditioners, and the
L, U, factors need to be non-singular. I think that Octave is right when it
says that a pivot is 0. I would change the %!xtest into a %!error and the
comment to % Matlab R2017b returns a singular L.
