TESTING/LIN/cchklq.f(3) 🦋

okay bestie, this page is from the Library Functions Manual, and the star of the show is TESTING/LIN/cchklq.f(3). It’s giving “serious numerical testing but make it cute,” and we’re keeping every single detail, no cap. 💅✨

🔥 Purpose 🔥

okay so the whole point: CCHKLQ tests CGELQF, CUNGLQ and CUNMLQ. Periodt. That’s the purpose, and it ate. 💖

🍓 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. 🎀
• NM — NM is INTEGER. The number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M.
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix column dimension N.
• 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). 🦋
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB.
• NXVAL — NXVAL is INTEGER array, dimension (NNB). The values of the crossover point NX.
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system.
• 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. 🫶
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• 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).
• TAU — TAU is COMPLEX array, dimension (NMAX).
• WORK — WORK is COMPLEX array, dimension (NMAX*NMAX).
• RWORK — RWORK is REAL array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. 📌

okurrr, that’s the whole page — footer sign-off vibes: LAPACK, Version 3.12.0, page TESTING/LIN/cchklq.f(3). The footer doesn’t hand me a date to copy, so I’m not inventing one, bestie — mwah 💋✨
