		proxsuite::linalg::sparse::SymbolicMatRef< I >	CT )

inline

Constructor using the symbolic factorization.

Parameters

results	solver's results.
data	solver's model.
settings	solver's settings.
precond_req	storage requirements for the solver's preconditioner.
H	symbolic structure of the quadratic cost input defining the QP model.
