TESTING/EIG/dckglm.f(3)

🌸 NAME 🌸

Okay bestie, this page is TESTING/EIG/dckglm.f — header title TESTING/EIG/dckglm.f(3) — straight out of the Library Functions Manual. It's the dckglm subroutine's main character moment. 💅

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

   subroutine dckglm (nn, mval, pval, nval, nmats, iseed, thresh, nmax, a,
           af, b, bf, x, work, rwork, nin, nout, info)
           DCKGLM

💅 Function/Subroutine Documentation 💅

   subroutine dckglm (integer nn, integer, dimension( * ) mval, integer,
       dimension( * ) pval, integer, dimension( * ) nval, integer nmats,
       integer, dimension( 4 ) iseed, double precision thresh, integer nmax,
       double precision, dimension( * ) a, double precision, dimension( * ) af,
       double precision, dimension( * ) b, double precision, dimension( * ) bf,
       double precision, dimension( * ) x, double precision, dimension( * )
       work, double precision, dimension( * ) rwork, integer nin, integer nout,
       integer info)
       DCKGLM

🧚 Purpose 🧚

DCKGLM tests DGGGLM — the subroutine for solving the generalized linear model problem. That's the whole assignment, bestie. No cap. ✨

🍓 Parameters 🍓

• NN — INTEGER. The number of values of N, M and P contained in the vectors NVAL, MVAL and PVAL. 🎀
• MVAL — INTEGER array, dimension (NN). The values of the matrix column dimension M.
• PVAL — INTEGER array, dimension (NN). The values of the matrix column dimension P.
• NVAL — INTEGER array, dimension (NN). The values of the matrix row dimension N.
• NMATS — INTEGER. The number of matrix types to be tested for each combination of matrix dimensions. If NMATS >= NTYPES (the maximum number of matrix types), then all the different types are generated for testing. If NMATS < NTYPES, another input line is read to get the numbers of the matrix types to be used.
• ISEED — INTEGER array, dimension (4). On entry, the seed of the random number generator. The array elements should be between 0 and 4095, otherwise they will be reduced mod 4096, and ISEED(4) must be odd. On exit, the next seed in the random number sequence after all the test matrices have been generated.

Heads up, bestie: ISEED(4) must be odd — that's not a vibe, that's a rule. 💀

• THRESH — DOUBLE PRECISION. The threshold value for the test ratios. A result is included in the output file if RESID >= THRESH. To have every test ratio printed, use THRESH = 0.

THRESH = 0 is the "print everything" setting. Iconic. 🔥

• NMAX — INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — DOUBLE PRECISION array, dimension (NMAX*NMAX). 🦋
• AF — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• BF — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• X — DOUBLE PRECISION array, dimension (4*NMAX).
• RWORK — DOUBLE PRECISION array, dimension (NMAX).
• WORK — DOUBLE PRECISION array, dimension (NMAX*NMAX).
• NIN — INTEGER. The unit number for input.
• NOUT — INTEGER. The unit number for output.
• INFO — INTEGER. = 0 : successful exit. > 0 : If DLATMS returns an error code, the absolute value of it is returned.
