CCKGLM(3)

Hey bestie!! You're looking at CCKGLM(3) from the Library Functions Manual 💅✨ The header path is /home/abui...IG/cckglm.f(3) (yes, it shows up twice in the original header — we love a double-tap 🫶).

🌸 NAME 🌸

This NAME section is lowkey literally just the file path, ngl:

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

Slay, that's the whole vibe 🦋

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

The one subroutine in here is CCKGLM, and here's the signature exactly:

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

It also says CCKGLM again right after, because main character energy 👑

🦋 Function/Subroutine Documentation 🦋

Full typed-out signature, every type and dimension preserved — it's giving meticulous:

subroutine CCKGLM (integer nn, integer, dimension( * ) nval, integer,
    dimension( * ) mval, integer, dimension( * ) pval, integer nmats,
    integer, dimension( 4 ) iseed, real thresh, integer nmax, complex,
    dimension( * ) a, complex, dimension( * ) af, complex, dimension( * ) b,
    complex, dimension( * ) bf, complex, dimension( * ) x, complex,
    dimension( * ) work, real, dimension( * ) rwork, integer nin, integer
    nout, integer info)

And the name again: CCKGLM 💅

💖 Purpose 💖

It highkey tests CGGGLM, the subroutine for solving the generalized linear model problem. The original doc-comment is literally:

!>
!> CCKGLM tests CGGGLM - subroutine for solving generalized linear
!>                       model problem.

🎀 Parameters 🎀

Okay bestie, parameter roll call 🍓 in order, no skipping — this is the main event, fr fr:

• NN — INTEGER. The number of values of N, M and P contained in the vectors NVAL, MVAL and PVAL 💖
• NVAL — INTEGER array, dimension (NN). The values of the matrix row dimension N.
• 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.
• 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.
• THRESH — REAL. 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 — INTEGER. The maximum value permitted for M or N, used in dimensioning the work arrays.
• A — COMPLEX array, dimension (NMAX*NMAX).
• AF — COMPLEX array, dimension (NMAX*NMAX).
• B — COMPLEX array, dimension (NMAX*NMAX).
• BF — COMPLEX array, dimension (NMAX*NMAX).
• X — COMPLEX array, dimension (4*NMAX).
• RWORK — REAL array, dimension (NMAX).
• WORK — COMPLEX 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 CLATMS returns an error code, the absolute value of it is returned. (error-code caveat, iykyk)

Okay that's the whole page, bestie! ✨ cute sign-off ✨ LAPACK, Version 3.12.0, and the footer path is /home/abui...IG/cckglm.f(3) — the original footer has no date, so I'm not inventing one 🙈💜🦋
