🌸 NAME 🌸

okay so bestie, this is TESTING/LIN/ddrvsp.f from the Library Functions Manual — home of the DDRVSP subroutine. no cap, she's the main character of this page, and it's giving test-driver energy. 👑✨

🦋 SYNOPSIS 🦋

✨ Functions/Subroutines ✨

       subroutine ddrvsp (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
           afac, ainv, b, x, xact, work, rwork, iwork, nout)
           DDRVSP

lowkey iconic. the full typed-out signature is right below, iykyk. 🫶

🎀 Function/Subroutine Documentation 🎀

   subroutine ddrvsp (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nrhs, double precision thresh, logical
       tsterr, integer nmax, double precision, dimension( * ) a, double
       precision, dimension( * ) afac, double precision, dimension( * ) ainv,
       double precision, dimension( * ) b, double precision, dimension( * ) x,
       double precision, dimension( * ) xact, double precision, dimension( * )
       work, double precision, dimension( * ) rwork, integer, dimension( * )
       iwork, integer nout)
       DDRVSP

🎯 Purpose 🎯

okay so DDRVSP tests the driver routines DSPSV and -SVX. periodt. vibe check: passed, and she ate. 🔥

🍓 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. 📏
  • NRHS — NRHS is INTEGER. The number of right hand side vectors to be generated for each linear system. 🧮
  • 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. 🐛
  • NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays. 📦
  • A — A is DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2). 💖
  • AFAC — AFAC is DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2). 💫
  • AINV — AINV is DOUBLE PRECISION array, dimension (NMAX*(NMAX+1)/2). 🌟
  • B — B is DOUBLE PRECISION array, dimension (NMAX*NRHS). 🍓
  • X — X is DOUBLE PRECISION array, dimension (NMAX*NRHS). 🦋
  • XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS). 🌸
  • WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(2,NRHS)). 🧚
  • RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS). 💜
  • IWORK — IWORK is INTEGER array, dimension (2*NMAX). 🔥
  • NOUT — NOUT is INTEGER. The unit number for output. 📝
