Detailed Description

template<uni20::Real Scalar, typename Vector>
struct uni20::krylov::NonsymmetricEigenResult< Scalar, Vector >

Matrix-free nonsymmetric eigenvalue result.

For real nonsymmetric Arnoldi, eigenvalues may be complex even though vectors and matrix-vector products are real. Real eigenvectors are populated only when every selected Ritz value is numerically real. If any selected Ritz value is complex or ambiguous, right_eigenvectors is left empty and callers should inspect status and reality. Complex eigenvector output and real Schur two-plane output are reserved for later nonsymmetric phases.
