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

okay bestie, buckle up, because this one is a whole subroutine and she's lowkey iconic 🎀

🌸 NAME 🌸

TESTING/LIN/cchkql.f — yes that's literally the whole name, she's a file and she knows it 💅

✨ SYNOPSIS ✨

CCHKQL 🫶

🎀 Purpose: 🎀

CCHKQL tests CGEQLF, CUNGQL and CUNMQL.

that's it, that's the whole purpose, and honestly? she ate 🔥

⭐ Parameters ⭐

  • DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). it's giving ✨which matrix types are we testing✨ — matrices of type j (for 1 <= j <= NTYPES) get tested if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used, simple as that bestie 💅
  • NM — NM is INTEGER. it's the number of values of M contained in the vector MVAL. count them, queen 🔢
  • MVAL — MVAL is INTEGER array, dimension (NM). these are the values of the matrix row dimension M. rows girlies rise 🌈
  • NN — NN is INTEGER. the number of values of N contained in the vector NVAL. yes there are two N's in this name and no, that's not a typo 😭
  • NVAL — NVAL is INTEGER array, dimension (NN). the values of the matrix column dimension N. columns, periodt 💜
  • NNB — NNB is INTEGER. the number of values of NB and NX contained in the vectors NBVAL and NXVAL. the blocking parameters are used in pairs (NB,NX) — they're a duo, a package deal, main character energy 👑
  • NBVAL — NBVAL is INTEGER array, dimension (NNB). the values of the blocksize NB. block it out 💀
  • NXVAL — NXVAL is INTEGER array, dimension (NNB). the values of the crossover point NX. the crossover episode, literally 🧚
  • NRHS — NRHS is INTEGER. the number of right hand side vectors to be generated for each linear system. how many RHS besties are coming to the party 🍓
  • THRESH — THRESH is REAL. the threshold value for the test ratios, aka the vibe check ✅ — a result is included in the output file if RESULT >= THRESH. and if you want every test ratio printed, use THRESH = 0, no gatekeeping 🫶
  • TSTERR — TSTERR is LOGICAL. flag that indicates whether error exits are to be tested. do we test the error exits or not, that's the question 🙈
  • NMAX — NMAX is INTEGER. the maximum value permitted for M or N, used in dimensioning the work arrays. she's the ceiling, the limit, the standard 🌟
  • A — A is COMPLEX array, dimension (NMAX*NMAX) 🌸
  • AF — AF is COMPLEX array, dimension (NMAX*NMAX) 🦋
  • AQ — AQ is COMPLEX array, dimension (NMAX*NMAX) 💖
  • AL — AL is COMPLEX array, dimension (NMAX*NMAX) 🎀
  • AC — AC 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) — the exact one, she's precise, she's that girl 💅
  • TAU — TAU is COMPLEX array, dimension (NMAX) 🌈
  • WORK — WORK is COMPLEX array, dimension (NMAX*NMAX) — put in the work, get the results, iykyk 🔥
  • RWORK — RWORK is REAL array, dimension (NMAX) — the real one (literally) 🍓
  • NOUT — NOUT is INTEGER. the unit number for output. where the receipts get printed 📠

lowkey a reminder: everything above is straight from the source, no cap — I didn't invent a single flag, number, or array dimension. copy the signatures exactly or the compiler will simply not forgive you 😭

okay that's the whole page, you're welcome, go forth and test those QL routines 💖
