Bundle of the matrices/vectors that define one augmented-system instance. Lives only for the duration of the call. Mirrors the long argument list of upstream AugSystemSolver::Solve.

Fields

w: Option<&'a dyn SymMatrix>

Hessian-of-Lagrangian block. None means W = 0 (used by LeastSquareMults and the resto-NLP equality multiplier estimate).

w_factor: Number

Multiplier on W (typically 1.0; restoration uses ζ).

d_x: Option<&'a dyn Vector>

D_x, the (1,1) primal weight diagonal. None means zero.

delta_x: Number

d_s: Option<&'a dyn Vector>

D_s, the (2,2) slack weight diagonal. None means zero.

delta_s: Number

j_c: &'a dyn Matrix

Equality-constraint Jacobian, m_c × n_x.

d_c: Option<&'a dyn Vector>

D_c, the (3,3) diagonal weight. None means zero. Goes in with a negative sign, matching upstream.

delta_c: Number

j_d: &'a dyn Matrix

Inequality-constraint Jacobian, m_d × n_x.

d_d: Option<&'a dyn Vector>

D_d, the (4,4) diagonal weight. None means zero. Goes in with a negative sign, matching upstream.

delta_d: Number
