💖 ZDRVGE(3) — Library Functions Manual 💖

okay bestie, welcome to the ZDRVGE(3) page — yes, it's from the Library Functions Manual, and yes, it's giving “LAPACK test-driver for the ZGESV and -SVX girlies.” It's a Fortran subroutine doc, so grab a lil snack and let's get into it. ✨

🎯 Purpose 🎯

!>
!> ZDRVGE tests the driver routines ZGESV and -SVX.

Translation for the group chat: this is the test agenda for ZGESV and -SVX, periodt. 💅

🔥 Parameters 🔥

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It's the matrix-type guest list: 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. Very “invited or not invited,” no cap. 🎟️
• NN — NN is INTEGER. It's the number of values of N contained in the vector NVAL. Literally the count of N values we're working with. ✨
• NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix column dimension N. The main-character numbers, basically. 👑
• NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. RHS besties, assembled per system. 🫶
• 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, set it to zero and let it spill. 🍵
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. A lil yes/no for the error-exit vibe check. ✅
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. Big N energy goes here. 🔥
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX). That's the whole spec for this one — iconic, brief, done. 💅
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*NMAX). Another NMAX*NMAX situation, slay. ✨
• ASAV — ASAV is COMPLEX*16 array, dimension (NMAX*NMAX). Yes bestie, same dimension, different array name. 🎀
• B — B is COMPLEX*16 array, dimension (NMAX*NRHS). Right-hand-side storage has entered the chat. 🦋
• BSAV — BSAV is COMPLEX*16 array, dimension (NMAX*NRHS). The save-file twin of B, basically. 💾
• X — X is COMPLEX*16 array, dimension (NMAX*NRHS). The solution-ish array, dimensioned exactly like that. ⭐
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS). Exact array, exact same dimension energy. 💜
• S — S is DOUBLE PRECISION array, dimension (2*NMAX). Note the 2*NMAX, bestie — don't shrink it. 🌸
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NRHS)). The work array said “I contain multitudes, but specifically NMAX*max(3,NRHS).” 😭
• RWORK — RWORK is DOUBLE PRECISION array, dimension (2*NRHS+NMAX). Real work array, exact dimension, no edits. 🧚
• IWORK — IWORK is INTEGER array, dimension (NMAX). Integer work array, cute and simple. 🌈
• NOUT — NOUT is INTEGER. The unit number for output. Where the test results go to be seen. 📬
