CCHKPP(3)

💅 CCHKPP(3) — like, the library functions manual page for cchkpp.f

okay bestie, so this is page cchkpp.f(3) out of the Library Functions Manual, and the path up top literally reads /home/abui...IN/cchkpp.f(3) — yes it's truncated, no I can't fix it, that's just how it's printed, iykyk ✨

🌸 NAME 🌸

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

that's the whole name. it's a Fortran file. she's an icon, she's a path, she contains multitudes 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine CCHKPP (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax,
    a, afac, ainv, b, x, xact, work, rwork, nout)

CCHKPP

🎯 Purpose 🎯

!> !> CCHKPP tests CPPTRF, -TRI, -TRS, -RFS, and -CON !>

like, she's the vibe-checker for the whole CPPTR* family — CPPTRF, -TRI, -TRS, -RFS, and -CON. all five. she tests them. periodt. 🔥

💖 Parameters 💖

• DOTYPE — !> DOTYPE is LOGICAL array, dimension (NTYPES). !> 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. 💅 so basically it's the guest list: type j only gets to come to the party if DOTYPE(j) is .TRUE. — otherwise she's not on the list, no cap.
• NN — !> NN is INTEGER. !> The number of values of N contained in the vector NVAL. so like, how many N's are we even talking about 🫶
• NVAL — !> NVAL is INTEGER array, dimension (NN). !> The values of the matrix dimension N. the actual N's, bestie. the dimensions. iconic.
• NNS — !> NNS is INTEGER. !> The number of values of NRHS contained in the vector NSVAL. same energy as NN, but for right-hand sides 🌈
• NSVAL — !> NSVAL is INTEGER array, dimension (NNS). !> The values of the number of right hand sides NRHS. the NRHS values themselves, living their truth ✨
• 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. okay so this is the whole gatekeeping situation: if RESULT >= THRESH, it goes in the output file. and if you want literally everything printed — every single ratio, no filter, main character energy — set THRESH = 0. 💀
• TSTERR — !> TSTERR is LOGICAL. !> Flag that indicates whether error exits are to be tested. are we testing the error exits or not, that's the question 🧚
• NMAX — !> NMAX is INTEGER. !> The maximum value permitted for N, used in dimensioning the !> work arrays. the ceiling. the limit. the largest N allowed, and she's literally the reason the work arrays are sized the way they are 👑
• A — !> A is COMPLEX array, dimension !> (NMAX*(NMAX+1)/2) ✨
• AFAC — !> AFAC is COMPLEX array, dimension !> (NMAX*(NMAX+1)/2) 🎀
• AINV — !> AINV is COMPLEX array, dimension !> (NMAX*(NMAX+1)/2) 🦋
• 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(NMAX,2*NSMAX)) 💅
• NOUT — !> NOUT is INTEGER. !> The unit number for output. where the results go to be seen, periodt 🌟

okay and the lil sign-off at the bottom of the page: LAPACK, Version 3.12.0, and the source path /home/abui...IN/cchkpp.f(3) — that's the whole footer, mwah, bye bestie 💖🎀🦋
