bestie, you found the Library Functions Manual page for SCHKSY_RK and it is so much Fortran testing lore ✨ no cap, this one is a whole test-driver subroutine, and we're gonna walk it together.

🌸 NAME 🌸

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

That's the file, periodt. 💅

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine SCHKSY_RK (dotype, nn, nval, nnb, nbval, nns, nsval, thresh,
     tsterr, nmax, a, afac, e, ainv, b, x, xact, work, rwork, iwork,
     nout)
     SCHKSY_RK

🫶 Function/Subroutine Documentation 🫶

subroutine SCHKSY_RK (logical, dimension( * ) dotype, integer nn, integer,
     dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
     nns, integer, dimension( * ) nsval, real thresh, logical tsterr, integer

     SCHKSY_RK

🎯 Purpose 🎯

the Doxygen purpose literally says:

!> SCHKSY_RK tests SSYTRF_RK, -TRI_3, -TRS_3, and -CON_3.

so yeah, it's testing SSYTRF_RK, -TRI_3, -TRS_3, and -CON_3. iconic. 🔥

🧸 Parameters 🧸

• DOTYPE — 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 — INTEGER. The number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN). The values of the matrix dimension N.
• NNB — INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — INTEGER array, dimension (NNB). The values of the blocksize NB.
• NNS — INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• THRESH — 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 — 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 — REAL array, dimension (NMAX*NMAX).
• AFAC — REAL array, dimension (NMAX*NMAX).
• E — REAL array, dimension (NMAX).
• AINV — REAL array, dimension (NMAX*NMAX).
• B — REAL array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• X — REAL array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• XACT — REAL array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• WORK — REAL array, dimension (NMAX*max(3,NSMAX)).
• RWORK — REAL array, dimension (max(NMAX,2*NSMAX)).
• IWORK — INTEGER array, dimension (2*NMAX).
• NOUT — INTEGER. The unit number for output.
