Functions
std::expected< Inverse, Failure >	serif::solver::preconditioner::backend::mfem::try_identity (int size)
	Prepare an identity inverse on a nonempty coordinate block.
std::expected< Inverse, Failure >	serif::solver::preconditioner::backend::mfem::try_diagonal_inverse (std::span< const double > diagonal)
	Own the reciprocal of every finite nonzero entry, including signed diagonals.
std::expected< Inverse, Failure >	serif::solver::preconditioner::backend::mfem::try_diagonal_inverse (std::span< const double > diagonal, const strategies::inverse::Diagonal &options)
	Apply an explicitly requested signed floor before preparing the same immutable diagonal inverse.
