Detailed Description

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

LU factorization of a real square general tridiagonal matrix.

Uses LAPACK gttrf storage. second_upper_diagonal has length n - 2 when n >= 2; pivot_rows stores LAPACK row pivots as zero-based row indices.

Template Parameters

Scalar

Real scalar type.
