Detailed Description

template<uni20::LapackReal Scalar>
struct uni20::krylov::RealSymmetricPositiveDefiniteTridiagonalFactorization< Scalar >

Cholesky factorization of a real SPD tridiagonal matrix.

Uses LAPACK pttrf storage: the diagonal is overwritten by the diagonal D factor, and the offdiagonal stores the unit bidiagonal factor multipliers.

Template Parameters

Scalar

Real scalar type.
