ALAHD
ALAHD prints header information for the different test paths.
[in] | IOUNIT | IOUNIT is INTEGER The unit number to which the header information should be printed. |
[in] | PATH | PATH is CHARACTER*3 The name of the path for which the header information is to be printed. Current paths are _GE: General matrices _GB: General band _GT: General Tridiagonal _PO: Symmetric or Hermitian positive definite _PS: Symmetric or Hermitian positive semi-definite _PP: Symmetric or Hermitian positive definite packed _PB: Symmetric or Hermitian positive definite band _PT: Symmetric or Hermitian positive definite tridiagonal _SY: Symmetric indefinite, with partial (Bunch-Kaufman) pivoting _SR: Symmetric indefinite, with rook (bounded Bunch-Kaufman) pivoting _SK: Symmetric indefinite, with rook (bounded Bunch-Kaufman) pivoting ( new storage format for factors: L and diagonal of D is stored in A, subdiagonal of D is stored in E ) _SP: Symmetric indefinite packed, with partial (Bunch-Kaufman) pivoting _HA: (complex) Hermitian , with Aasen Algorithm _HE: (complex) Hermitian indefinite, with partial (Bunch-Kaufman) pivoting _HR: (complex) Hermitian indefinite, with rook (bounded Bunch-Kaufman) pivoting _HK: (complex) Hermitian indefinite, with rook (bounded Bunch-Kaufman) pivoting ( new storage format for factors: L and diagonal of D is stored in A, subdiagonal of D is stored in E ) _HP: (complex) Hermitian indefinite packed, with partial (Bunch-Kaufman) pivoting _TR: Triangular _TP: Triangular packed _TB: Triangular band _QR: QR (general matrices) _LQ: LQ (general matrices) _QL: QL (general matrices) _RQ: RQ (general matrices) _QP: QR with column pivoting _TZ: Trapezoidal _LS: Least Squares driver routines _LU: LU variants _CH: Cholesky variants _QS: QR variants _QT: QRT (general matrices) _QX: QRT (triangular-pentagonal matrices) _TS: QR routines for tall-skinny and short-wide matrices _HH: Householder reconstruction for tall-skinny matrices The first character must be one of S, D, C, or Z (C or Z only if complex). |
