Detailed Description

Packed Band Matrix (LAPACK PB storage format)

Storage format for symmetric positive definite band matrices. Uses LAPACK routines DPBTRF, DPBTRS. Only stores upper triangle (ku superdiagonals).

Constructor & Destructor Documentation

◆ PBMat()

orb5x::spclibs::PBMat::PBMat ( )

default

Construct an empty, unallocated packed-band descriptor.

Member Function Documentation

◆ is_initialized()

bool orb5x::spclibs::PBMat::is_initialized ( ) const

inline

Returns: true when packed-band storage is allocated.

References val.

◆ lda()

int orb5x::spclibs::PBMat::lda ( ) const

inline

Returns: LAPACK packed-band leading dimension ku+1.

References ku.

Member Data Documentation

◆ kmat

int orb5x::spclibs::PBMat::kmat = 0

Matrix identifier.

◆ ku

int orb5x::spclibs::PBMat::ku = 0

Number of superdiagonals.

Referenced by lda().

◆ nterms

int orb5x::spclibs::PBMat::nterms = 0

Number of non-zero terms.

◆ rank

int orb5x::spclibs::PBMat::rank = 0

Matrix rank (= number of rows/columns)

◆ val

Kokkos::View<Real**, Kokkos::HostSpace> orb5x::spclibs::PBMat::val
