nk::linalg::cdf2rdf
std::tuple< Value, Value > cdf2rdf(const Value &V, const Value &D, std::pmr::memory_resource *mr=nullptr)
Complex-diagonal → real-block-diagonal Schur form ([VR, DR] = cdf2rdf(V, D)).
nk::linalg::rsf2csf
std::tuple< Value, Value > rsf2csf(const Value &UR, const Value &TR, std::pmr::memory_resource *mr=nullptr)
Real Schur → complex Schur form ([U, T] = rsf2csf(UR, TR)).
