CERRED(3)

💅 CERRED(3) — like, the error-exit tester for complex eigenvalue drivers 🎀

ok so real talk, this page lives in the Library Functions Manual, bestie. And the file it's documenting is this whole gorgeous path:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/cerred.f

like yes, that's the whole thing, she's long, she's iconic, we respect her 💖

✨ SYNOPSIS ✨

Functions/Subroutines 🦋

• subroutine CERRED (path, nunit) — CERRED. that's it, that's the vibe.

🌸 Function/Subroutine Documentation 🌸

subroutine CERRED (character*3 path, integer nunit) 💫

CERRED.

🎯 Purpose:

ngl bestie, this is what she does:

!>
!> CERRED tests the error exits for the eigenvalue driver routines for
!> REAL matrices:
!>
!> PATH  driver   description
!> ----  ------   -----------
!> CEV   CGEEV    find eigenvalues/eigenvectors for nonsymmetric A
!> CES   CGEES    find eigenvalues/Schur form for nonsymmetric A
!> CVX   CGEEVX   CGEEV + balancing and condition estimation
!> CSX   CGEESX   CGEES + balancing and condition estimation
!> CBD   CGESVD   compute SVD of an M-by-N matrix A
!>       CGESDD   compute SVD of an M-by-N matrix A(by divide and
!>                conquer)
!>       CGEJSV   compute SVD of an M-by-N matrix A where M >= N
!>       CGESVDX  compute SVD of an M-by-N matrix A(by bisection
!>                and inverse iteration)
!>       CGESVDQ  compute SVD of an M-by-N matrix A(with a
!>                QR-Preconditioned )
!>

(and yes the table says "REAL matrices" — I'm just the messenger, don't come for me 😭💀)

🧸 Parameters

• PATH — !> PATH is CHARACTER*3 — !> The LAPACK path name for the routines to be tested. 🍓 like, the three-letter vibe check that tells her which driver to poke at.
• NUNIT — !> NUNIT is INTEGER — !> The unit number for output. 🔥 where all the tea gets printed.

and that's the whole page, bestie — no cap, nothing skipped, every last flag and path accounted for 💅

signing off with love from LAPACK Version 3.12.0, dated /home/abui...IG/cerred.f(3) — mwah, bye! 💖✨🎀
