TESTING/LIN/dchktp.f(3)

💖 NAME 💖

TESTING/LIN/dchktp.f — okay so this is the manual page for that file, straight out of the Library Functions Manual, and it's giving Fortran test-realness in the best way. 🫶

✨ SYNOPSIS ✨

🌈 Functions/Subroutines 🌈

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

🦋 Function/Subroutine Documentation 🦋

subroutine dchktp (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
    precision thresh, logical tsterr, integer nmax, double precision,
    dimension( * ) ap, double precision, dimension( * ) ainvp, double
    precision, dimension( * ) b, double precision, dimension( * ) x, double
    precision, dimension( * ) xact, double precision, dimension( * ) work,
    double precision, dimension( * ) rwork, integer, dimension( * ) iwork,
    integer nout)
    DCHKTP

🎯 Purpose 🎯

DCHKTP tests DTPTRI, -TRS, -RFS, and -CON, and DLATPS. Slay. ✨

🧚 Parameters 🧚

• DOTYPE — a LOGICAL array, dimension (NTYPES). It says which matrix types get used for testing. Type j (for 1 <= j <= NTYPES) is used if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. No cap. 💅
• NN — INTEGER; the number of values of N contained in the vector NVAL.
• NVAL — INTEGER array, dimension (NN); the values of the matrix column dimension N.
• 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 — 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. Set it to zero if you want the whole group chat. 😭
• TSTERR — LOGICAL; flag that indicates whether error exits are to be tested.
• NMAX — INTEGER; the leading dimension of the work arrays. NMAX >= the maximum value of N in NVAL.
• AP — DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• AINVP — DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2).
• B — DOUBLE PRECISION array, dimension (NMAX*NSMAX), where NSMAX is the largest entry in NSVAL.
• X — DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• XACT — DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• WORK — DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)).
• IWORK — INTEGER array, dimension (NMAX).
• RWORK — DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• NOUT — INTEGER; the unit number for output.
