🎀 NAME 🎀

TESTING/LIN/cdrvhe_rk.f — bestie, this is the LAPACK test-driver file (manual name: Library Functions Manual), and it's literally the whole vibe of "does CHESV_RK actually work or are we just trusting 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, the main character 👑
subroutine cdrvhe_rk (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
    nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
    dimension( * ) e, complex, dimension( * ) ainv, complex, dimension( * )
    b, complex, dimension( * ) x, complex, dimension( * ) xact, complex,
    dimension( * ) work, real, dimension( * ) rwork, integer, dimension( * )
    iwork, integer nout)

CDRVHE_RK — yep, that's the name again, no notes 🫶

💖 Function/Subroutine Documentation 💖

🌈 Purpose

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

okay so that's the whole job description: it runs the vibes check on CHESV_RK's driver routines. That's it. That's the mission. periodt 🦋

⭐ 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. — it's your guest list, bestie: type j gets tested only if DOTYPE(j) is .TRUE.; if it's .FALSE. then type j is literally not invited to the function 💀
  • NN — !> NN is INTEGER !> The number of values of N contained in the vector NVAL. — how many N values are sitting in NVAL. simple as 🍓
  • NVAL — !> NVAL is INTEGER array, dimension (NN) !> The values of the matrix dimension N. — the actual N values, i.e. the matrix dimensions we're serving looks at 🔥
  • NRHS — !> NRHS is INTEGER !> The number of right hand side vectors to be generated for !> each linear system. — how many right-hand-side vectors get generated per linear system, no cap 🧚
  • 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. — the gatekeeper 🚪 a result makes it into the output file only if RESULT >= THRESH. want every single test ratio printed? set THRESH = 0. icon behavior.
  • TSTERR — !> TSTERR is LOGICAL !> Flag that indicates whether error exits are to be tested. — a flag saying whether we're testing the error exits too 🙈
  • NMAX — !> NMAX is INTEGER !> The maximum value permitted for N, used in dimensioning the !> work arrays. — the max allowed N, and it's what sizes the work arrays 💜
  • A — !> A is COMPLEX array, dimension (NMAX*NMAX) — the matrix itself, COMPLEX, sized (NMAX*NMAX) ✨
  • AFAC — !> AFAC is COMPLEX array, dimension (NMAX*NMAX) — the factored version of A, COMPLEX, sized (NMAX*NMAX) 💅
  • E — !> E is COMPLEX array, dimension (NMAX) — COMPLEX, dimension (NMAX), short and sweet 🎀
  • AINV — !> AINV is COMPLEX array, dimension (NMAX*NMAX) — the inverse-ish storage, COMPLEX, dimension (NMAX*NMAX) 🔥
  • B — !> B is COMPLEX array, dimension (NMAX*NRHS) — COMPLEX, dimension (NMAX*NRHS) — the right-hand sides live here 🦋
  • X — !> X is COMPLEX array, dimension (NMAX*NRHS) — COMPLEX, dimension (NMAX*NRHS), the computed solution spot 🌸
  • XACT — !> XACT is COMPLEX array, dimension (NMAX*NRHS) — COMPLEX, dimension (NMAX*NRHS) — the exact solution, for comparison purposes 👑
  • WORK — !> WORK is COMPLEX array, dimension (NMAX*max(2,NRHS)) — COMPLEX, dimension (NMAX*max(2,NRHS)) — note that max(2,NRHS), don't forget it 😭
  • RWORK — !> RWORK is REAL array, dimension (NMAX+2*NRHS) — REAL this time, dimension (NMAX+2*NRHS) 🌈
  • IWORK — !> IWORK is INTEGER array, dimension (NMAX) — INTEGER, dimension (NMAX) ⭐
  • NOUT — !> NOUT is INTEGER !> The unit number for output. — the unit number where all the output goes 📤
