CCHKGE(3)

🦋 CCHKGE(3) — like, the LAPACK testing page for CCHKGE bestie 💅

okay so real talk, this is a page from the Library Functions Manual (cchkge.f(3)) and it's basically the vibe check for one very busy Fortran test subroutine. buckle up 🎀

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cchkge.f

that's the whole name, no cap — it's a path, it's long, it's giving "my file system is a main character" 😭 don't retype it by hand, copy it fr fr.

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine CCHKGE (dotype, nm, mval, nn, nval, nnb, nbval, nns, nsval,
    thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork,
    nout)

CCHKGE 🫶 that's it, that's the subroutine.

👑 Function/Subroutine Documentation 👑

subroutine CCHKGE (logical, dimension( * ) dotype, integer nm, integer,
    dimension( * ) mval, integer nn, integer, dimension( * ) nval, integer
    nnb, integer, dimension( * ) nbval, integer nns, integer, dimension( * )
    nsval, real thresh, logical tsterr, integer nmax, complex, dimension( * )
    a, complex, dimension( * ) afac, complex, dimension( * ) ainv,
    complex, dimension( * ) b, complex, dimension( * ) x, complex,
    dimension( * ) xact, complex, dimension( * ) work, real, dimension( * )
    rwork, integer, dimension( * ) iwork, integer nout)

CCHKGE — yes it's named twice, she contains multitudes 💜

🎯 Purpose:

!>
!> CCHKGE tests CGETRF, -TRI, -TRS, -RFS, and -CON.
!>

so she's out here testing five routines in one go: CGETRF, -TRI, -TRS, -RFS, and -CON. highkey an overachiever, we love to see it 🔥

💖 Parameters 💖

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). it's the guest list basically: the matrix types to be used for testing. matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. 🙈
• NM — NM is INTEGER. the number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). the values of the matrix row dimension M. 📏
• NN — NN is INTEGER. the number of values of N contained in the vector NVAL.
• NVAL — NVAL is INTEGER array, dimension (NN). the values of the matrix column dimension N. 📐
• NNB — NNB is INTEGER. the number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). the values of the blocksize NB. 🧱
• NNS — NNS is INTEGER. the number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). the values of the number of right hand sides NRHS. 🫱
• THRESH — THRESH is REAL. 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. ⭐ (yes, zero means "show me everything", iconic behaviour)
• TSTERR — TSTERR is LOGICAL. flag that indicates whether error exits are to be tested. 🚩
• NMAX — NMAX is INTEGER. the maximum value permitted for M or N, used in dimensioning the work arrays. 📦
• A — A is COMPLEX array, dimension (NMAX*NMAX).
• AFAC — AFAC is COMPLEX array, dimension (NMAX*NMAX).
• AINV — AINV is COMPLEX array, dimension (NMAX*NMAX).
• B — B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. 💙
• X — X is COMPLEX array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX array, dimension

(NMAX*max(3,NSMAX))

• RWORK — RWORK is REAL array, dimension

(max(2*NMAX,2*NSMAX+NWORK))

• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. the unit number for output. 🖨️

fr fr bestie, this page is auto-generated, so don't come for me about the typos — Doxygen did that 💀

and that's the whole page!! 💅 LAPACK, Version 3.12.0, living at /home/abui...IN/cchkge.f(3) — mwah, bye 🍓💜
