Classes
class	serif::solver::normalization::backend::mfem::detail::ScaledOperator< Inverse >
	Common algebra for a Jacobian L J S^-1 and an inverse S M^-1 L^-1. More...
struct	serif::solver::normalization::backend::mfem::ScaledPreconditionerStatistics
	Counts physical bindings and normalized applications without instrumenting the inverse itself. More...
class	serif::solver::normalization::backend::mfem::ScaledPreconditioner
	MFEM solver adapter which always binds the physical inverse to its dimensional Jacobian. More...

Typedefs
using	serif::solver::normalization::backend::mfem::ScaledJacobianOperator = detail::ScaledOperator<false>
	Normalized Jacobian L J S^-1.
using	serif::solver::normalization::backend::mfem::ScaledInverseOperator = detail::ScaledOperator<true>
	Normalized physical inverse S M^-1 L^-1.

Functions
int	serif::solver::normalization::backend::mfem::detail::mfem_size (std::size_t size)
	Translate a prepared coordinate size without narrowing beyond MFEM's index range.
void	serif::solver::normalization::backend::mfem::detail::scale_vector (std::span< const double > factors, const ::mfem::Vector &input, ::mfem::Vector &output, bool inverse)
	Apply a diagonal to MFEM host storage, resizing only after the input has been checked.
