🎀 TESTING/LIN/sdrvpt.f 🎀

okay so bestie, this is a page from the LAPACK manual — the TESTING/LIN/sdrvpt.f file specifically — and it's lowkey just documenting one little Fortran subroutine that runs test suites. Let's get into it 💅

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine sdrvpt (dotype, nn, nval, nrhs, thresh, tsterr, a, d, e, b,
    x, xact, work, rwork, nout)

SDRVPT — that's the whole vibe, that's the name 🫶

🌸 Function/Subroutine Documentation 🌸

subroutine sdrvpt (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, real,
    dimension( * ) a, real, dimension( * ) d, real, dimension( * ) e, real,
    dimension( * ) b, real, dimension( * ) x, real, dimension( * ) xact,
    real, dimension( * ) work, real, dimension( * ) rwork, integer nout)

SDRVPT

Purpose 💖

SDRVPT tests SPTSV and -SVX.

no cap, that's literally the entire purpose statement. it's giving "short and iconic" ✨

Parameters 🎀

okay so here's the full roster, no skips, no cuts, main character energy for every single one:

  • DOTYPE — 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 — INTEGER. The number of values of N contained in the vector NVAL.
  • NVAL — INTEGER array, dimension (NN). The values of the matrix dimension N.
  • NRHS — INTEGER. The number of right hand side vectors to be generated for each linear system. bestie these are the lil' solution vectors okay 🫶
  • THRESH — 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. (yes literally every single one, it's gonna be a lot 💀)
  • TSTERR — LOGICAL. Flag that indicates whether error exits are to be tested.
  • A — REAL array, dimension (NMAX*2).
  • D — REAL array, dimension (NMAX*2).
  • E — REAL array, dimension (NMAX*2).
  • B — REAL array, dimension (NMAX*NRHS).
  • X — REAL array, dimension (NMAX*NRHS).
  • XACT — REAL array, dimension (NMAX*NRHS).
  • WORK — REAL array, dimension (NMAX*max(3,NRHS)).
  • RWORK — REAL array, dimension (max(NMAX,2*NRHS)).
  • NOUT — INTEGER. The unit number for output.
