DCKGLM(3)

💖 DCKGLM(3) — LAPACK Library Functions Manual 💖

Okay so welcome to the <pink>LAPACK Library Functions Manual</pink>, bestie — this page is a whole test-driver situation and it's lowkey packed with parameters, so grab a strawberry 🍓 and let's go.

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/dckglm.f

That's the file this whole page is about — periodt. 💅

✨ 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 📜

Here's the full typed-out signature, bestie — copy it exactly or it won't slay:

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 🎯

The source comment says it plainly: DCKGLM tests DGGGLM - subroutine for solving generalized linear model problem. So yeah, it's the test for DGGGLM, and that's the generalized linear model problem. Iconic. ✨

🧮 Parameters 🧮

• NN — NN is INTEGER. It's the number of values of N, M and P contained in the vectors NVAL, MVAL and PVAL.
• MVAL — MVAL is INTEGER array, dimension (NN). The values of the matrix column dimension M.
• PVAL — PVAL is INTEGER array, dimension (NN). The values of the matrix column dimension P.
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix row dimension N.
• NMATS — NMATS is 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 — ISEED is 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.
• THRESH — THRESH is 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.
• NMAX — NMAX is INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — A is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• AF — AF is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• BF — BF is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• X — X is DOUBLE PRECISION array, dimension (4*NMAX).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*NMAX).
• NIN — NIN is INTEGER. The unit number for input.
• NOUT — NOUT is INTEGER. The unit number for output.
• INFO — INFO is INTEGER. Exit status, bestie:
  • = 0 : successful exit
  • > 0 : If DLATMS returns an error code, the absolute value of it is returned.
