TESTING/LIN/zchkgt.f(3) 🦋

okay so this page is from the Library Functions Manual, and it's literally the tea on ZCHKGT — no cap. Buckle up bestie, we're checking complex general tridiagonal stuff and the tests are gonna slay. 💅

NAME ✨

TESTING/LIN/zchkgt.f

SYNOPSIS 🎀

Functions/Subroutines 💖

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

Function/Subroutine Documentation 💜

   subroutine zchkgt (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, logical tsterr, complex*16, dimension( * ) a,
       complex*16, dimension( * ) af, complex*16, dimension( * ) b, complex*16,
       dimension( * ) x, complex*16, dimension( * ) xact, complex*16, dimension(
       * ) work, double precision, dimension( * ) rwork, integer,
       dimension( * ) iwork, integer nout)
       ZCHKGT

Purpose 🔥

ZCHKGT tests ZGTTRF, -TRS, -RFS, and -CON. That's the whole vibe. ✨

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. 🫶
  • 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 dimension N. 🌸
  • 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 DOUBLE PRECISION. 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. Flag that indicates whether error exits are to be tested. 💅
  • A — A is COMPLEX*16 array, dimension (NMAX*4). ⭐
  • AF — AF is COMPLEX*16 array, dimension (NMAX*4). 💫
  • B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. 🌈
  • X — X is COMPLEX*16 array, dimension (NMAX*NSMAX). 🧚
  • XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX). 💜
  • WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)). 🔥
  • RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX)+2*NSMAX). 🌸
  • IWORK — IWORK is INTEGER array, dimension (NMAX). 🎀
  • NOUT — NOUT is INTEGER. The unit number for output. 🫶
