💅 /home/abui...IN/alahd.f(3) — Library Functions Manual 💅

okay bestie, this is the Library Functions Manual page for /home/abui...IN/alahd.f(3) — yes, the title path is abbreviated like that, and we are rolling with it. It’s all about the ALAHD testing subroutine, and it’s lowkey the hype woman for LAPACK’s test paths. ✨

🎀 NAME 🎀

/home/abuild/rpmbuild/BUILD/lapack-
static-3.12.0-build/lapack-3.12.0/TESTING/LIN/alahd.f

(the man page wrapped that path over two lines; I’m keeping it exactly as it appeared, no edits, periodt.)

🦋 SYNOPSIS 🦋

🧚 Functions/Subroutines 🧚

  • subroutine ALAHD (iounit, path) — ALAHD

🌸 Function/Subroutine Documentation 🌸

🎀 subroutine ALAHD (integer iounit, character*3 path) 🎀

ALAHD

✨ Purpose ✨

ALAHD prints header information for the different test paths.

🧸 Parameters 🧸

IOUNIT

IOUNIT is INTEGER The unit number to which the header information should be printed.

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).
