Detailed Description

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

LAPACK general band storage for a real square matrix.

storage uses LAPACK gbtrf/gbtrs factor-storage layout with 2 * lower_bandwidth + upper_bandwidth + 1 rows and order columns. Original matrix entries are stored at row lower_bandwidth + upper_bandwidth + i - j in column j.

Template Parameters

Scalar

Real scalar type.
