It is possible to adapt the problem while generating the Hopf curve.
This call updates the auxiliary variables used in the defining system of the computed branch. The bordering
matrices
and
may require updating since they must at least be such that the matrix in (62) is nonsingular. Updating
of
and
is done exactly as in the LP case.
Updating of
is done in such a way that the linearized system of (61) is
as well-conditioned as possible.
