okay so bestie, this is a page from the Library Functions Manual — LAPACK's Fortran test-driver territory, fr fr. It's a .f file living deep in the TESTING/LIN folder, and it's literally the vibe-check machine for CHESV_RK. Let's get into it 💅

✨ SYNOPSIS ✨

🌸 Functions/Subroutines

subroutine CDRVHE_RK (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, e, ainv, b, x, xact, work, rwork, iwork, nout)

CDRVHE_RK — that's the whole name, no notes, she said what she said 👑

💖 Function/Subroutine Documentation 💖

    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer

CDRVHE_RK 🦋 (yes it says its own name twice, she's iconic like that)

🔥 Purpose:

!>
!> CDRVHE_RK tests the driver routines CHESV_RK.
!>

So basically: this subroutine is the certified tester for CHESV_RK. She runs the checks, she reports the results. main character energy tbh 🌟

💜 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). The matrix types to be used for testing. Matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. so it's the guest list, and if you're not on it you're not getting in 🙈
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL. it's giving "how many sizes are we testing today" ✨
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N. all the sizes, lined up, ready to go 💅
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. how many RHS besties are we making per system 🫶
• THRESH — THRESH is REAL. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0. lowkey the strictness setting — set it to 0 and she prints everything, no filter, no cap 😭
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. do we test the bad-path drama or not 💀
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. the ceiling, the limit, the "don't go past this" line 🌈
• A — A is COMPLEX array, dimension (NMAX*NMAX)
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX)
• E — E is COMPLEX array, dimension (NMAX)
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX)
• B — B is COMPLEX array, dimension (NMAX*NRHS)
• X — X is COMPLEX array, dimension (NMAX*NRHS)
• XACT — XACT is COMPLEX array, dimension (NMAX*NRHS)
• WORK — WORK is COMPLEX array, dimension (NMAX*max(2,NRHS))
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS)
• IWORK — IWORK is INTEGER array, dimension (NMAX)
• NOUT — NOUT is INTEGER. The unit number for output. where the receipts get printed, periodt 🧾

ngl bestie, all those work arrays have exact dimensions for a reason — do not resize them, do not get creative, she will notice 💀
