TESTING/LIN/cchksy_rk.f(3)

💅 NAME

TESTING/LIN/cchksy_rk.f — like, this is the LAPACK test file for the symmetric-indefinite ✨rk✨ factorization routines, and it lives in the Library Functions Manual bestie 🎀

🌸 SYNOPSIS

Functions/Subroutines

subroutine cchksy_rk (dotype, nn, nval, nnb, nbval, nns, nsval, thresh,
    tsterr, nmax, a, afac, e, ainv, b, x, xact, work, rwork, iwork,
    nout)

CCHKSY_RK 👑

    dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
    nns, integer, dimension( * ) nsval, real thresh, logical tsterr, integer
    nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,

CCHKSY_RK — yes bestie, that's the whole signature, we love a long parameter list, it's giving main character energy 🫶

💜 Purpose:

!>
!> CCHKSY_RK tests CSYTRF_RK, -TRI_3, -TRS_3,
!> and -CON_3.
!>

So it's the vibe-check squad for four routines at once: CSYTRF_RK, -TRI_3, -TRS_3, and -CON_3. Iconic behavior, honestly 🔥

🎀 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are the matrix types we're testing with, mmkay. Matrices of type j (for 1 <= j <= NTYPES) get used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is simply not used. Not invited to the party 💅
• NN — NN is INTEGER. It's how many values of N are chillin' inside the vector NVAL. 🍓
• NVAL — NVAL is INTEGER array, dimension (NN). These are the actual values of the matrix dimension N. The whole point of the operation ✨
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL. Count 'em.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB 🧚
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL. Number of right hand sides energy.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS 👑
• THRESH — THRESH is REAL. Here's the threshold value for the test ratios. A result gets included in the output file if RESULT >= THRESH. Want every single test ratio printed? Use THRESH = 0. No filter, no gatekeeping 💖
• TSTERR — TSTERR is LOGICAL. A flag that says whether error exits are to be tested. Yes or no bestie.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, and it's used in dimensioning the work arrays. Bigger NMAX, bigger arrays, that's the whole deal.
• 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) — the inverse storage, slay
• B — B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. Read that twice, it matters 😭
• X — X is COMPLEX array, dimension (NMAX*NSMAX) 💜
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX) — the exact solution, the blueprint, the reference
• WORK — WORK is COMPLEX array, dimension (NMAX*max(3,NSMAX)) 🔥
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)) 🌸
• IWORK — IWORK is INTEGER array, dimension (2*NMAX) 🦋
• NOUT — NOUT is INTEGER. The unit number for output. Where all the tea gets printed 💅

ok so that's literally the whole page bestie, every last array dimension accounted for, no cap 🙈

Sign-off ✨💖 — this cutie was auto-generated by Doxygen for LAPACK from the source code, and the page is straight out of LAPACK Version 3.12.0 for TESTING/LIN/cchksy_rk.f(3). Go forth and test those _RK routines, queen 👑💅
