TESTING/LIN/zchkhe_aa.f(3) 💅

okay so bestie, welcome to the zchkhe_aa page — straight outta the LAPACK Library Functions Manual, and yes it's a whole mood. this is the one that stress-tests the _AA variants of the Hermitian factorization + solve routines. buckle up 🎀

✨ NAME ✨

TESTING/LIN/zchkhe_aa.f — like, that's literally the file, that's the name, periodt.

⭐ Purpose ⭐

!> !> ZCHKHE_AA tests ZHETRF_AA, -TRS_AA. !>

so like. it tests ZHETRF_AA and ZHETRF_AA's bestie -TRS_AA. that's the whole assignment, no cap 💖

🎀 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. it's giving guest list with a bouncer 🚪✨
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL. literally how many N's we're running today 💅
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix dimension N. all the sizes, lined up like a little runway 👑
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL. the blocksize headcount 🧮
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB. block sizes, iconic, no notes 🔥
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL. how many right-hand-side counts we're test-driving 🌈
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS. the actual NRHS numbers, bestie 🍓
• THRESH — THRESH is DOUBLE PRECISION. 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. so if you want the FULL tea spilled, set it to 0 — otherwise it's giving ✨filtered✨
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. we do a lil vibe check on the error paths too 🕵️‍♀️
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. the ceiling, the limit, the "know your place" number 💀
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX). the matrix herself 💖
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX). the factored version, main character energy 🫶
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*NMAX). the inverse, slaying in her own lane 🦋
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. the right-hand sides, all lined up 🌸
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX). the solution vibes ✨
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX). the exact one, the reference, the standard 🎯
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)). workspace, doing the unpaid labor as always 😭
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)). the real-valued workspace, keeping it grounded 🌱
• IWORK — IWORK is INTEGER array, dimension (NMAX). integer workspace, small but mighty 💜
• NOUT — NOUT is INTEGER. The unit number for output. where all the receipts get printed 🧾
