EqualityConstrainedQPSolver Class Reference

Detailed Description

Solves a quadratic program with equality constraint.

This program doesn't depend on the initial guess.

The user can set the following options:

• FeasibilityTolOptionName(). The feasible solution (both primal and dual variables) should satisfy their constraints, with error no larger than this value. The default is Eigen::dummy_precision().
