Detailed Description

Linear system solvers for the bound-constrained QP formulation. Contains material common to the sparse and dense variants (though in this distribution we provide the implementation only of the dense variant).

Member Function Documentation

void QpBoundLinsys::factor (  Data *    prob, Variables *    vars )  [virtual]

sets up the matrix for the main linear system. The actual factorization is performed by a routine specific to either the sparse or dense case. See also: QpBoundDenseLinsys::factor Implements LinearSystem. Reimplemented in QpBoundDenseLinsys.

void QpBoundLinsys::solve (  Data *    prob, Variables *    vars, Residuals *    rhs, Variables *    step )  [virtual]

solve the system for the given set of redisuals Implements LinearSystem.
