ZDRVSP(3)

okay bestie, this is ZDRVSP(3) from the Library Functions Manual — buckle up, we're getting into one very specific LAPACK test driver 💅✨

🌸 NAME 🌸

the source file is literally:

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

✨ SYNOPSIS ✨

Functions/Subroutines

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

💅 Function/Subroutine Documentation 💅

   subroutine ZDRVSP (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, integer nmax, complex*16, dimension( * ) a, complex*16,
       dimension( * ) afac, complex*16, dimension( * ) ainv, complex*16,
       dimension( * ) b, complex*16, dimension( * ) x, complex*16, dimension( *
       ) xact, complex*16, dimension( * ) work, double precision, dimension( *
       ) rwork, integer, dimension( * ) iwork, integer nout)
       ZDRVSP

🎀 Purpose 🎀

okay so the purpose is literally: ZDRVSP tests the driver routines ZSPSV and -SVX. that's the whole assignment, bestie. iconic. 💖

🌈 Parameters 🌈

• DOTYPE — LOGICAL array, dimension (NTYPES). these are the matrix types we're testing. for type j (where 1 <= j <= NTYPES), matrices of type j are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. vibe check complete 🫶.
• NN — INTEGER. the number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). the values of the matrix dimension N.
• NRHS — INTEGER. the number of right hand side vectors to be generated for each linear system.
• THRESH — 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.
• TSTERR — LOGICAL. flag that indicates whether error exits are to be tested.
• NMAX — INTEGER. the maximum value permitted for N, used in dimensioning the work arrays.
• A — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AFAC — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AINV — COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• B — COMPLEX*16 array, dimension (NMAX*NRHS).
• X — COMPLEX*16 array, dimension (NMAX*NRHS).
• XACT — COMPLEX*16 array, dimension (NMAX*NRHS).
• WORK — COMPLEX*16 array, dimension (NMAX*max(2,NRHS)).
• RWORK — DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
• IWORK — INTEGER array, dimension (NMAX).
• NOUT — INTEGER. the unit number for output.

and that's the whole page! cute sign-off: the footer says LAPACK Version 3.12.0 and the source path is /home/abui...IN/zdrvsp.f(3). there's no date in the footer, just pure LAPACK energy and good vibes. bye 💖🦋✨🎀
