auto Reaktoro::KktSolver::solve ( const KktVector rhs,
KktSolution sol 
) -> void

Solve the KKT equation using an appropriate and efficient approach according to a priori decomposition call.

The KKT equation is solved using an LU decomposition if the matrices H and A are dense. A rangespace approach is used instead if either the inverse of the H matrix is known or it has a diagonal structure. Finally, if the matrix A has been specified to be constant, then an efficient nullspace approach is used to reduce the system of linear equations.

Parameters
rhsThe right-hand side vector of the KKT equation
solThe solution vector of the KKT equation
