SDRVPT(3)

okay so this is SDRVPT(3) from the LAPACK Library Functions Manual, and it lives in /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/sdrvpt.f. It's giving test-driver energy, and we're gonna go through every single arg together. 💅

🌸 NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/sdrvpt.f — that's the source file path, bestie, and SDRVPT(3) is the manual page you're reading. No cap. 🫶

✨ SYNOPSIS

okay so the callable vibe is a subroutine, and the synopsis is literally:

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

🎀 Functions/Subroutines

There's exactly one entry here, and it's this icon:

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

🦋 Function/Subroutine Documentation

here's the full signature, character-for-character, bestie:

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)

and the name on the tin is SDRVPT. periodt. 💖

🎯 Purpose

fr fr the purpose is:

!>
!> SDRVPT tests SPTSV and -SVX.

💖 Parameters

okay bestie, this is the parameter parade. Every single one, no skipping:

• 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 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.
• TSTERR — TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.
• A — A is REAL array, dimension (NMAX*2).
• D — D is REAL array, dimension (NMAX*2).
• E — E is REAL array, dimension (NMAX*2).
• B — B is REAL array, dimension (NMAX*NRHS).
• X — X is REAL array, dimension (NMAX*NRHS).
• XACT — XACT is REAL array, dimension (NMAX*NRHS).
• WORK — WORK is REAL array, dimension (NMAX*max(3,NRHS)).
• RWORK — RWORK is REAL array, dimension (max(NMAX,2*NRHS)).
• NOUT — NOUT is INTEGER. The unit number for output.
