CDRVHE_AA_2STAGE(3)

💅 CDRVHE_AA_2STAGE(3) 💅

okay so welcome to the Library Functions Manual bestie, this one's a whole LAPACK internal testing file and honestly it's giving "backstage pass" energy 🎟️✨

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cdrvhe_aa_2stage.f

like yes that's the whole name, it's a path, she's long, she's iconic, we don't shorten her 💅

CDRVHE_AA_2STAGE

💖 Purpose 💖

okay so real talk: CDRVHE_AA_2STAGE tests the driver routine CHESV_AA_2STAGE. That's it. That's the job. She's the vibe-checker for the actual solver, and she takes her role very seriously 🔥

🎀 Parameters 🎀

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). This is the guest list, bestie: it says which matrix types get 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 literally not invited. not used. blocked. 🙈
• NN — NN is INTEGER. It's the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N. like the size menu 🍓
• 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. (yes, 0 means "show me everything", she's not shy 💀)
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV 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).
• WORK — WORK is COMPLEX array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. like where she posts her results 📮

okay and for the little sign-off moment: this whole page is LAPACK, Version 3.12.0, and the footer path is /home/abui...aa_2stage.f(3) — that's a wrap bestie, go test some matrices, ily, periodt 🫶🎀✨
