💅 TESTING/LIN/schktr.f(3) — from the Library Functions Manual, bestie ✨

ok so picture this: you're deep in TESTING/LIN/schktr.f and you need to know what this whole thing does. do not panic. i got you. 🫶

SCHKTR

✨ Purpose ✨

SCHKTR tests STRTRI, -TRS, -RFS, and -CON, and SLATRS(3)

like literally the whole triangular squad gets a vibe check 💅

💖 Parameters 💖

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). it's 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 basically it's the guest list 🎟️
• NN — NN is INTEGER. it's the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). these are the values of the matrix column dimension N. iconique.
• NNB — NNB is INTEGER. the number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). the values of the blocksize NB. yes bestie, blocksize matters ✨
• NNS — NNS is INTEGER. the number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). the values of the number of right hand sides NRHS. right hand sides, not right hand swipes 🙈
• 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 "show me everything" button 👀
• TSTERR — TSTERR is LOGICAL. flag that indicates whether error exits are to be tested. we LOVE a dramatic exit 💀
• NMAX — NMAX is INTEGER. the leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL. no cap on that comparison, it's a hard requirement fr fr.
• A — A is REAL array, dimension (NMAX*NMAX)
• AINV — AINV is REAL array, dimension (NMAX*NMAX)
• B — B is REAL array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is REAL array, dimension (NMAX*NSMAX)
• XACT — XACT is REAL array, dimension (NMAX*NSMAX)
• WORK — WORK is REAL array, dimension (NMAX*max(3,NSMAX))
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX))
• IWORK — IWORK is INTEGER array, dimension (NMAX)
• NOUT — NOUT is INTEGER. the unit number for output. that's where the receipts go 🧾

mkay that's the whole page, you ate that 🍓 stay hydrated, read your manpages, and remember: LAPACK Version 3.12.0, dated TESTING/LIN/schktr.f(3) — mwah 💋💖
