ZERRST(3)

💅 ZERRST(3) — like, the error-exit test for all your favorite Hermitian routines

okay bestie, so this one lives in the Library Functions Manual, and the page literally points at /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/zerrst.f — that's the file, that's the whole NAME section, we move 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine ZERRST (path, nunit) — ZERRST, that's her, that's the icon

🦋 Function/Subroutine Documentation 🦋

subroutine ZERRST (character*3 path, integer nunit)

ZERRST. periodt. 💅

🧚 Purpose:

ZERRST tests the error exits for ZHETRD, ZHETD2, ZUNGTR, CUNMTR, ZHPTRD, ZUNGTR, ZUPMTR, ZSTEQR, CSTEIN, ZPTEQR, ZHBTRD, ZHEEV, CHEEVX, CHEEVD, ZHBEV, CHBEVX, CHBEVD, ZHPEV, CHPEVX, CHEPVD, and ZSTEDC. ZHEEVD_2STAGE, ZHEEVR_2STAGE, ZHEEVX_2STAGE, ZHEEV_2STAGE, ZHBEV_2STAGE, ZHBEVD_2STAGE, ZHBEVX_2STAGE, ZHETRD_2STAGE

no cap, that's the whole list — every single one of those routines gets its error exits checked, and yes ZUNGTR shows up twice in the source and we're not gonna pretend it doesn't 😭 also CHEPVD not CHEEVD, don't @ me, that's literally what it says 🔥

🌸 Parameters

• PATH — PATH is CHARACTER*3, and it's the LAPACK path name for the routines to be tested. lowkey the whole vibe check for which family gets poked 🫶
• NUNIT — NUNIT is INTEGER, and it's the unit number for output. that's where all the tea gets printed 💖

and that's the whole page, mwah 💋 — this beauty ships with LAPACK Version 3.12.0, and the whole thing traces back to that zerrst.f(3) source path up top. go test those error exits, bestie, slay 🦋✨
