💖 TESTING/LIN/schktp.f — Library Functions Manual ✨

🌸 NAME

TESTING/LIN/schktp.f — that's the name, periodt. 💅

✨ SYNOPSIS

🎀 Functions/Subroutines

Here's the call, no cap:

subroutine schktp (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax,
    ap, ainvp, b, x, xact, work, rwork, iwork, nout)
    SCHKTP

🧚 Function/Subroutine Documentation

Here's the full typed signature — long, iconic, and exactly what the source says:

subroutine schktp (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nns, integer, dimension( * ) nsval, real
    thresh, logical tsterr, integer nmax, real, dimension( * ) ap, real,
    dimension( * ) ainvp, real, dimension( * ) b, real, dimension( * ) x,
    real, dimension( * ) xact, real, dimension( * ) work, real, dimension( *
    ) rwork, integer, dimension( * ) iwork, integer nout)
    SCHKTP

🌈 Purpose

SCHKTP tests STPTRI, -TRS, -RFS, and -CON, and SLATPS

That's the whole purpose, slay. 🔥

🫶 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It's the matrix-type menu: 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 column dimension N.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• 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 leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL.
• AP — AP is REAL array, dimension (NMAX*(NMAX+1)/2).
• AINVP — AINVP is REAL array, dimension (NMAX*(NMAX+1)/2).
• B — B is REAL array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is REAL array, dimension (NMAX*NSMAX).
• XACT — XACT is REAL array, dimension (NMAX*NSMAX).
• WORK — WORK is REAL array, dimension (NMAX*max(3,NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NSMAX)).
• NOUT — NOUT is INTEGER. The unit number for output. That's the output vibe check. 🍓

Sign-off, bestie: source/version is LAPACK Version 3.12.0, the page is TESTING/LIN/schktp.f(3), and the footer doesn't show a separate date — so I'm not inventing one. 🫶
