Domain-specific

• Frontal Solver
  • For symmetric positive-definite systems the factorization is commonly Cholesky; general unsymmetric or indefinite systems require LU-style forms and suitable stability controls.
  • If threshold pivoting delays several fully summed variables, the realized front can still exceed the symbolic estimate, so the solver records both predictions and observed peaks.
