💅 zchksy_aa: the vibe check 💅

okay bestie, welcome to TESTING/LIN/zchksy_aa.f from the LAPACK Library Functions Manual. This is the page for the subroutine that runs the ZCHKSY_AA test energy — it’s giving “I test things so you don’t have to,” and honestly? Iconic.

ZCHKSY_AA

✨ Purpose ✨

ZCHKSY_AA tests ZSYTRF_AA, -TRS_AA. That’s the whole purpose, and it ate. 💅

🔥 Parameters 🔥

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are the matrix types 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. No cap, it’s literally the guest list.
• NN — NN is INTEGER. This is 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. This is 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. This is 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 DOUBLE PRECISION. This is 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. Periodt — if you want the full receipts, set it to zero.
• TSTERR — TSTERR is LOGICAL. This flag indicates whether error exits are to be tested.
• NMAX — NMAX is INTEGER. This is the maximum value permitted for N, used in dimensioning the work arrays. It’s the main-character ceiling, bestie.
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is COMPLEX*16 array, dimension (max(NMAX,2*NSMAX)). Yes, that’s what the page says — I’m just reporting the vibe, not fixing Fortran for fun.
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. This is the unit number for output.
