💖 NAME 💖

Hi bestie 🫶 this is the page for /home/abui...chksy_aa.f(3) from the Library Functions Manual, and the actual file it's documenting is:

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

No cap, it's giving LAPACK testing file energy 💅.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines

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

SCHKSY_AA — that's the icon, the moment, the subroutine ✨.

🌸 Function/Subroutine Documentation 🌸

subroutine SCHKSY_AA (logical, dimension( * ) dotype, integer nn, integer, dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer nns, integer, dimension( * ) nsval, real thresh, logical tsterr, integer nmax, real, dimension( * ) a, real, dimension( * ) afac, real, dimension( * ) ainv, real, dimension( * ) b, real, dimension( * ) x, real, dimension( * ) xact, real, dimension( * ) work, real, dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)

Again: SCHKSY_AA. Repetition is literally the brand 💖.

🎯 Purpose

Lowkey the whole point: SCHKSY_AA tests SSYTRF_AA, -TRS_AA. That's it, that's the vibe check 🔥.

📝 Parameters

• DOTYPE — DOTYPE is a 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. Periodt.
• 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 dimension N ✨.
• NNB — NNB is INTEGER. It's the number of values of NB contained in the vector NBVAL 🌸.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). These are the values of the blocksize NB 🎀.
• NNS — NNS is INTEGER. It's the number of values of NRHS contained in the vector NSVAL 🦋.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). These are the values of the number of right hand sides NRHS 💜.
• THRESH — THRESH is REAL. It's 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 N, used in dimensioning the work arrays 🔥.
• A — A is REAL array, dimension (NMAX*NMAX) ⭐.
• AFAC — AFAC 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 (2*NMAX) 🧚.
• NOUT — NOUT is INTEGER. The unit number for output 👑.

Parameter list ate, no crumbs 🍓.
