💖 NAME 💖

okay so this is the TESTING/LIN/cchkgt.f(3) page from the Library Functions Manual, bestie — and the subroutine living inside it is CCHKGT, our main character for this whole little testy-test arc ✨

✨ SYNOPSIS ✨

Functions/Subroutines — yes, that’s the category label, and here’s the exact synopsis:

subroutine cchkgt (dotype, nn, nval, nns, nsval, thresh, tsterr, a, af,
    b, x, xact, work, rwork, iwork, nout)
    CCHKGT

🎀 Function/Subroutine Documentation 🎀

Here’s the full signature, typed out exactly, no cap:

subroutine cchkgt (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nns, integer, dimension( * ) nsval, real
    thresh, logical tsterr, complex, dimension( * ) a, complex, dimension( *
    ) af, complex, dimension( * ) b, complex, dimension( * ) x, complex,
    dimension( * ) xact, complex, dimension( * ) work, real, dimension( * )
    rwork, integer, dimension( * ) iwork, integer nout)
    CCHKGT

🌸 Purpose 🌸

Bestie, the assignment is right here: CCHKGT tests CGTTRF, -TRS, -RFS, and -CON. That’s the whole purpose, periodt 💅

🦋 Parameters 🦋

  • DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are 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. 🎀
  • NN — NN is INTEGER. It’s the number of values of N contained in the vector NVAL. ✨
  • NVAL — NVAL is INTEGER array, dimension (NN). These are the values of the matrix dimension N. 💖
  • NNS — NNS is INTEGER. It’s the number of values of NRHS contained in the vector NSVAL. 🦋
  • NSVAL — NSVAL is INTEGER array, dimension (NNS). These are the values of the number of right hand sides NRHS. 🌸
  • THRESH — THRESH is REAL. It’s 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. 👑
  • TSTERR — TSTERR is LOGICAL. This flag indicates whether error exits are to be tested. 🔥
  • A — A is COMPLEX array, dimension (NMAX*4). 💜
  • AF — AF is COMPLEX array, dimension (NMAX*4). ✨
  • 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). 🦋
  • IWORK — IWORK is INTEGER array, dimension (NMAX). 💖
  • NOUT — NOUT is INTEGER. It’s the unit number for output. 💅
