Okay bestie, welcome to TESTING/LIN/zdrvpt.f(3)! This page lives in the Library Functions Manual, and it’s all about the zdrvpt subroutine. 💅

🌸 NAME 🌸

TESTING/LIN/zdrvpt.f

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

The whole callable is right here, bestie — types, dimensions, and all:

       subroutine zdrvpt (logical, dimension( * ) dotype, integer nn, integer,
           dimension( * ) nval, integer nrhs, double precision thresh, logical
           tsterr, complex*16, dimension( * ) a, double precision, dimension( * )
           d, complex*16, dimension( * ) e, complex*16, dimension( * ) b,
           complex*16, dimension( * ) x, complex*16, dimension( * ) xact,
           complex*16, dimension( * ) work, double precision, dimension( * ) rwork,
           integer nout)
           ZDRVPT

🦋 Function/Subroutine Documentation 🦋

Here’s the same zdrvpt signature in the documentation’s own layout, plus the ZDRVPT name drop:

   subroutine zdrvpt (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, complex*16, dimension( * ) a, double precision, dimension( * )
       d, complex*16, dimension( * ) e, complex*16, dimension( * ) b,
       complex*16, dimension( * ) x, complex*16, dimension( * ) xact,
       complex*16, dimension( * ) work, double precision, dimension( * ) rwork,
       integer nout)
       ZDRVPT

🧚 Purpose 🧚

ZDRVPT tests ZPTSV and -SVX. That’s the purpose, no cap. ✨

🌈 Parameters 🌈

  • DOTYPE — DOTYPE is 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. 🫶
  • 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.
  • NRHS — NRHS is INTEGER. It’s the number of right hand side vectors to be generated for each linear system.
  • THRESH — THRESH is DOUBLE PRECISION. 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. (Zero is the “show me everything” setting, bestie. 🔥)
  • TSTERR — TSTERR is LOGICAL. This flag indicates whether error exits are to be tested.
  • A — A is COMPLEX*16 array, dimension (NMAX*2).
  • D — D is DOUBLE PRECISION array, dimension (NMAX*2).
  • E — E is COMPLEX*16 array, dimension (NMAX*2).
  • B — B is COMPLEX*16 array, dimension (NMAX*NRHS).
  • X — X is COMPLEX*16 array, dimension (NMAX*NRHS).
  • XACT — XACT is COMPLEX*16 array, dimension (NMAX*NRHS).
  • WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NRHS)).
  • RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS).
  • NOUT — NOUT is INTEGER. It’s the unit number for output.

Okay bestie, that’s the whole page. Footer source/version sign-off: LAPACK Version 3.12.0, page TESTING/LIN/zdrvpt.f(3). The footer doesn’t show a date, so I’m not inventing one — periodt. 💖✨
