Detailed Description

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

LAPACK symmetric positive-definite band storage for a real square matrix.

storage has bandwidth + 1 rows and order columns. For upper storage, original entries are stored at row bandwidth + i - j in column j for i <= j. For lower storage, original entries are stored at row i - j in column j for i >= j.

Template Parameters

Scalar

Real scalar type.
