ALADHD(3)

🌸 ALADHD(3) — Library Functions Manual 🌸

okay bestie, so this page is literally from the LAPACK manual (Library Functions Manual, mwah) and it's about a lil Fortran subroutine called ALADHD. She's a header-printing icon, nothing more, nothing less. And the source file is this whole journey:

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

like yes that's a real path, no I will not be shortening it 💅

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine ALADHD (iounit, path) — the whole vibe. That's it. That's the subroutine. ALADHD.

---

🎀 Function/Subroutine Documentation 🎀

subroutine ALADHD (integer iounit, character*3 path)

ALADHD. Again. She said what she said ✨

🦋 Purpose:

!>
!> ALADHD prints header information for the driver routines test paths.
!>

So basically she prints header info for the driver-routine test paths. That's her whole job and she eats every time 💖

💜 Parameters

IOUNIT

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

So IOUNIT is an INTEGER, and it's literally just the unit number where the header info gets printed. That's where the output goes, bestie 📬

PATH

!>          PATH is CHARACTER*3
!>          The name of the path for which the header information is to
!>          be printed.  Current paths are

okay so PATH is CHARACTER*3 and it's the name of the path you want headers for. Look at this lineup though, it's giving ✨menu✨:

• _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 , Assen 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

🚨 and the rule, do not skip it: the first character must be one of S, D, C, or Z — and C or Z only if it's complex. fr fr, that's a hard requirement.

💫 cute lil sign-off: this page is LAPACK Version 3.12.0, and yeah, the footer is still out here repping /home/abui...IN/aladhd.f(3) because some things never change. bye bestie, go print some headers 💅✨
