serif::solver::preconditioner::backend::mfem::detail::DirectLUPattern Class Reference

Symbolic analysis (fill-reducing ordering) of one sparsity pattern, shared by the numeric factorizations of every matrix with that pattern. Implemented by the backend chosen with the sparse_direct Meson option (direct_lu_accelerate.cpp, direct_lu_umfpack.cpp or direct_lu_none.cpp). More...

Detailed Description

Symbolic analysis (fill-reducing ordering) of one sparsity pattern, shared by the numeric factorizations of every matrix with that pattern. Implemented by the backend chosen with the sparse_direct Meson option (direct_lu_accelerate.cpp, direct_lu_umfpack.cpp or direct_lu_none.cpp).

Note

No backend type appears here: Accelerate's headers are not valid C++26 and are confined to a C++20 translation unit. A numeric factorization from a reused analysis equals a fresh factorization bit for bit (measured for both backends on potential blocks from different Newton states).
