TESTING/LIN/ddrvpt.f(3)

NAME 💖

okay bestie, this is the TESTING/LIN/ddrvpt.f(3) page from the Library Functions Manual. It's all about ddrvpt, and yes, we're getting into the LAPACK testing files. Slay.

SYNOPSIS 🎀

Functions/Subroutines ✨

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

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

Function/Subroutine Documentation 🦋

Here's the full signature, bestie, exactly as it appears:

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

And the name is DDRVPT. Main character energy, honestly.

Purpose 🌸

DDRVPT tests DPTSV and -SVX. That's the whole purpose. Iconic and concise.

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.
• A — A is DOUBLE PRECISION array, dimension (NMAX*2).
• D — D is DOUBLE PRECISION array, dimension (NMAX*2).
• E — E is DOUBLE PRECISION array, dimension (NMAX*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(3,NRHS)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NRHS)).
• NOUT — NOUT is INTEGER. The unit number for output.
