CCHKTZ(3)

💅 CCHKTZ — the vibe check for CTZRZF ✨

okay so real talk, bestie: this page lives in the Library Functions Manual, and its whole name-tag situation is cchktz.f(3). That's it, that's the title, we're moving on 🫶

🌸 NAME

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

yes the entire name section is just that absolute path 😭 it's giving "my name is my student ID". LAPACK said no nicknames, only filesystem. iconic honestly.

✨ SYNOPSIS

🎀 Functions/Subroutines

subroutine CCHKTZ (dotype, nm, mval, nn, nval, thresh, tsterr, a, copya,
    s, tau, work, rwork, nout)
    CCHKTZ

that's the whole call, no cap — fourteen arguments, one subroutine, zero chill 💀

    dimension( * ) mval, integer nn, integer, dimension( * ) nval, real
    thresh, logical tsterr, complex, dimension( * ) a, complex, dimension( *

look at that signature, she's gorgeous, she's thorough, she has opinions about array dimensions 🦋

💖 Purpose

!>
!> CCHKTZ tests CTZRZF.
!>

short king behavior. literally two lines. CCHKTZ is the test driver for CTZRZF, and that's the entire purpose, periodt ✨

🌈 Parameters

• DOTYPE — a LOGICAL array, dimension (NTYPES). these are the matrix types to test. matrices of type j (for 1 <= j <= NTYPES) get tested when DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is simply not used. goodbye type j, we hardly knew ye 🙈
• NM — INTEGER. how many values of M are chilling inside the vector MVAL.
• MVAL — INTEGER array, dimension (NM). these are the values of the matrix row dimension M. rows, bestie, the horizontal ones 📏
• NN — INTEGER. how many values of N are packed into the vector NVAL.
• NVAL — INTEGER array, dimension (NN). the values of the matrix column dimension N. columns! the vertical ones! we love a perpendicular moment 💅
• THRESH — REAL. the threshold value for the test ratios. a result gets included in the output file if RESULT >= THRESH. want every single test ratio printed? set THRESH = 0. full transparency mode, we stan 🎀
• TSTERR — LOGICAL. flag that says whether error exits are going to be tested. yes or no, bestie, pick one.
• A — COMPLEX array, dimension (MMAX*NMAX), where MMAX is the maximum value of M in MVAL and NMAX is the maximum value of N in NVAL. big array energy 🔥
• COPYA — COMPLEX array, dimension (MMAX*NMAX). it's the copy. of A. the name is doing a lot of work here and honestly? respect 🌸
• S — REAL array, dimension (min(MMAX,NMAX)). take the minimum, she's modest 🧚
• TAU — COMPLEX array, dimension (MMAX).
• WORK — COMPLEX array, dimension (MMAX*NMAX + 4*NMAX + MMAX). yes that's a real expression, yes you should copy it exactly, do not get creative in the kitchen ⭐
• RWORK — REAL array, dimension (2*NMAX).
• NOUT — INTEGER. the unit number for output, aka where the gossip gets printed 💜

heads up bestie: every array here is a dimension declaration, not a suggestion. pass the wrong size and that's on you, not on me 💀

okay that's the whole page!! this was generated for LAPACK, Version 3.12.0, and the footer stamp thingy is literally just /home/abui...IN/cchktz.f(3) again — yeah, they put the path in the date slot, we're not gonna question it, we're just gonna slay and log off 🦋💖🎀
