ZCKGLM(3)

💅 ZCKGLM(3) — like, the zckglm.f page from the Library Functions Manual, bestie

okay so this is the man page for /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/zckglm.f and it's filed under Library Functions Manual — yes the path is a whole journey, we love a long dramatic file path 💖

✨ NAME ✨

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

that's it. that's the name. she's long, she's iconic, she contains multitudes (and rpmbuild) 🎀

🦋 SYNOPSIS 🦋

Functions/Subroutines

• subroutine ZCKGLM (nn, nval, mval, pval, nmats, iseed, thresh, nmax, a, af, b, bf, x, work, rwork, nin, nout, info) — yes, that's a lot of arguments, no cap, she's a whole group chat

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

ZCKGLM (that's the name again, main character energy 👑)

🌸 Function/Subroutine Documentation 🌸

subroutine ZCKGLM

here's the full signature so you can see every single one of them lined up, fr fr:

subroutine ZCKGLM (integer nn, integer, dimension( * ) nval, integer,
    dimension( * ) mval, integer, dimension( * ) pval, integer nmats,
    integer, dimension( 4 ) iseed, double precision thresh, integer nmax,
    complex*16, dimension( * ) a, complex*16, dimension( * ) af, complex*16,
    dimension( * ) b, complex*16, dimension( * ) bf, complex*16, dimension(
    * ) x, complex*16, dimension( * ) work, double precision, dimension( * )
    rwork, integer nin, integer nout, integer info)

ZCKGLM

🧚 Purpose:

!>
!> ZCKGLM tests ZGGGLM - subroutine for solving generalized linear
!>                       model problem.
!>

so yeah, she's the vibe-checker for ZGGGLM — the subroutine that solves the generalized linear model problem. she tests it. that's her job. periodt ✨

💜 Parameters

• NN — NN is INTEGER. the number of values of N, M and P contained in the vectors NVAL, MVAL and PVAL. so like, how many test sizes are we running 💅
• NVAL — NVAL is INTEGER array, dimension (NN). the values of the matrix row dimension N. 🫶
• 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.
• NMATS — NMATS is INTEGER. the number of matrix types to be tested for each combination of matrix dimensions. okay so listen: if NMATS >= NTYPES (where NTYPES is 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. two modes, both slay 🦋
• 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. so she's giving you a whole character arc for your seed 🌈

the ISEED(4) must be odd thing is not a suggestion, bestie — it's a requirement 😭

• 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. yes, literally every single one. chaos mode, we love it 🔥
• NMAX — NMAX is INTEGER. the maximum value permitted for M or N, used in dimensioning the work arrays. she's the ceiling that keeps the work arrays from being too messy 💀
• A — A is COMPLEX*16 array, dimension (NMAX*NMAX) 🍓
• AF — AF is COMPLEX*16 array, dimension (NMAX*NMAX)
• B — B is COMPLEX*16 array, dimension (NMAX*NMAX)
• BF — BF is COMPLEX*16 array, dimension (NMAX*NMAX)
• X — X is COMPLEX*16 array, dimension (4*NMAX). note: four times, not one time. she needs room 💅
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX)
• WORK — WORK is COMPLEX*16 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. the receipts, and they go like this:
  • = 0 : successful exit ✨
  • > 0 : if ZLATMS returns an error code, the absolute value of it is returned. so a positive INFO is ZLATMS's bad day, passed along to you 🙈

aaaand that's the whole page, bestie! catch you on the flip side — this one's from LAPACK, Version 3.12.0, dated /home/abui...IG/zckglm.f(3) (that truncated path is literally how it's printed, don't come for me 😭). bye bestie, go test your generalized linear model problems responsibly 💖🎀🦋
