okay so bestie, this is the Library Functions Manual page for our fave Fortran test-driver file, and it is literally giving “deep LAPACK lore” energy. No cap, every detail below is here to stay. ✨

NAME 🎀

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

SYNOPSIS 🦋

Functions/Subroutines

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

---

Function/Subroutine Documentation 💅

subroutine CDRVHE_ROOK (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
    nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
    dimension( * ) ainv, complex, dimension( * ) b, complex, dimension( * )
    x, complex, dimension( * ) xact, complex, dimension( * ) work, real,
    dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
    CDRVHE_ROOK

---

Purpose: 🎯

okay so the main character moment here is simple: CDRVHE_ROOK tests the driver routines CHESV_ROOK. That’s the whole purpose, bestie. It’s giving “test the driver, leave no crumbs.” 💖

Parameters 🌸

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). It’s the guest list for matrix types: 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. Not invited, not showing up. 💅
• NN — NN is INTEGER. It’s the number of values of N contained in the vector NVAL. So iconic. 🎀
• NVAL — NVAL is an INTEGER array, dimension (NN). These are the values of the matrix dimension N. Periodt. ✨
• NRHS — NRHS is INTEGER. It’s the number of right hand side vectors to be generated for each linear system. Multiple right-hand sides? She said yes. 🫶
• THRESH — THRESH is REAL. It’s 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. Loud and thorough, love that. 🔥
• TSTERR — TSTERR is LOGICAL. It’s the flag that indicates whether error exits are to be tested. Error exits getting their own vibe check. 😭
• NMAX — NMAX is INTEGER. It’s the maximum value permitted for N, used in dimensioning the work arrays. Big-array energy. 👑
• A — A is a COMPLEX array, dimension (NMAX*NMAX). That’s the whole note, bestie. 🌈
• AFAC — AFAC is a COMPLEX array, dimension (NMAX*NMAX). Same size, same complex-array slay. ⭐
• AINV — AINV is a COMPLEX array, dimension (NMAX*NMAX). Another iconic (NMAX*NMAX) situation. 💜
• B — B is a COMPLEX array, dimension (NMAX*NRHS). Right-hand-side baddie. 🍓
• X — X is a COMPLEX array, dimension (NMAX*NRHS). The solve-vector cutie. 🧚
• XACT — XACT is a COMPLEX array, dimension (NMAX*NRHS). Exact-solution energy, no cap. 💖
• WORK — WORK is a COMPLEX array, dimension (NMAX*max(2,NRHS)). Work array with range, literally. ✨
• RWORK — RWORK is a REAL array, dimension (NMAX+2*NRHS). Real-array realness. 🎀
• IWORK — IWORK is an INTEGER array, dimension (NMAX). Integer-array icon. 🦋
• NOUT — NOUT is INTEGER. It’s the unit number for output. The output unit said “I’m the moment.” 💅
