Detailed Description

template<uni20::Real Scalar>
struct uni20::krylov::NonsymmetricEigenParams< Scalar >

Parameters for a native nonsymmetric eigenvalue solve.

Phase 4 starts with a real-double Arnoldi implementation. The API already exposes the real-mode policy needed by transfer-matrix workflows: a real matrix-free operator can preserve a real Arnoldi basis while detecting when wanted Ritz values require complex eigenvectors or a real Schur two-plane.
