Follow-up Comment #1, bug #39573 (project octave):
Hi,
your example is not correct, since B is not positive definite. On the other
hand, I think you are right and line 1275 (and 2238 and 3259) of eigs-base.cc
should be changed to
vector_product (b, workd+iptr(0)-1, dtmp);
as for the case ido == 2.
Marco
