✨ NAME ✨

TESTING/LIN/alahd.f — Library Functions Manual. This is the TESTING/LIN/alahd.f(3) page, bestie, and the manual name is folded in right here instead of copying that header line like a boring person. 💅

🌸 SYNOPSIS 🌸

Functions/Subroutines, coming at you:

Functions/Subroutines

subroutine alahd (iounit, path)
    ALAHD

and the full documented signature is down below — keep scrolling 🫶

🎀 Function/Subroutine Documentation 🎀

alahd — ALAHD

Full signature, character-for-character:

subroutine alahd (integer iounit, character*3 path)

ALAHD is the subroutine doing the header-printing thing. Iconic.

Purpose

The source wraps this in a Doxygen !> block, and the tea is: 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). periodt, that's the whole path menu 🦋
