TESTING/LIN/sdrvsyx.f(3)

💅 NAME 💅

okay so this is the page for TESTING/LIN/sdrvsyx.f(3), straight out of the Library Functions Manual — and yes bestie, it's a whole manual page for one Fortran test routine and it's lowkey iconic. 🫶

✨ SYNOPSIS ✨

Under Functions/Subroutines you get this absolute unit:

       subroutine sdrvsy (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
           afac, ainv, b, x, xact, work, rwork, iwork, nout)
           SDRVSYX

🫶 Function/Subroutine Documentation 🫶

Here's the full signature, no cap:

   subroutine sdrvsy (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, 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)
       SDRVSYX

🎀 Purpose 🎀

SDRVSY tests the driver routines SSYSV, -SVX, and -SVXX. 💅

Note bestie: this file is used only when the XBLAS are available, otherwise sdrvsy.f defines this subroutine. No cap, that's the whole vibe.

🌸 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. ✨
• NN — NN is INTEGER. 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.
• 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. 👀
• 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*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS).
• WORK — WORK is REAL array, dimension (NMAX*max(2,NRHS)).
• RWORK — RWORK is REAL array, dimension (NMAX+2*NRHS).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. 🖨️
