💖 NAME 💖

Okay so this is the TESTING/LIN/cchktz.f(3) page from the Library Functions Manual — all about the cchktz subroutine. It's giving LAPACK testing vibes, and we're here to spill the tea. ✨

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

🫶 FUNCTION/SUBROUTINE DOCUMENTATION 🫶

   subroutine cchktz (logical, dimension( * ) dotype, integer nm, integer,
       dimension( * ) mval, integer nn, integer, dimension( * ) nval, real
       thresh, logical tsterr, complex, dimension( * ) a, complex, dimension( *
       ) copya, real, dimension( * ) s, complex, dimension( * ) tau, complex,
       dimension( * ) work, real, dimension( * ) rwork, integer nout)
       CCHKTZ

🌸 Purpose 🌸

CCHKTZ tests CTZRZF. That's the whole purpose. Periodt. 💅

🎀 Parameters 🎀

  • DOTYPE — This is a LOGICAL array, dimension (NTYPES). It's 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. Simple as that. ✨
  • NM — NM is INTEGER. It's the number of values of M contained in the vector MVAL. Got it? 💖
  • MVAL — MVAL is INTEGER array, dimension (NM). These are the values of the matrix row dimension M. Slay. 👑
  • 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. 🌈
  • 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. Lowkey important. 🔥
  • TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested. 💀
  • A — A is 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 — COPYA is COMPLEX array, dimension (MMAX*NMAX). Another one. 🍓
  • S — S is REAL array, dimension (min(MMAX,NMAX)). Cute. 🧚
  • TAU — TAU is COMPLEX array, dimension (MMAX). 💜
  • WORK — WORK is COMPLEX array, dimension (MMAX*NMAX + 4*NMAX + MMAX). The math is mathing. ✨
  • RWORK — RWORK is REAL array, dimension (2*NMAX). 💖
  • NOUT — NOUT is INTEGER. The unit number for output. That's where the tea gets spilled. ☕
