TESTING/LIN/ddrvrf3.f(3)

okay so this is the TESTING/LIN/ddrvrf3.f page from the Library Functions Manual, and it’s giving “LAPACK documentation but make it cute.” 💅 No cap, every parameter, type, dimension, author, and line number is staying right here.

💖 NAME 💖

TESTING/LIN/ddrvrf3.f

That’s the whole NAME, bestie. Short, iconic, to the point. 🎀

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

subroutine ddrvrf3 (nout, nn, nval, thresh, a, lda, arf, b1, b2,

🫶 Function/Subroutine Documentation 🫶

Here’s the full signature, character-for-character, because we do not play fast and loose with Fortran around here:

subroutine ddrvrf3 (integer nout, integer nn, integer, dimension( nn ) nval,
     double precision thresh, double precision, dimension( lda, * ) a,
     integer lda, double precision, dimension( * ) arf, double precision,
     dimension( lda, * ) b1, double precision, dimension( lda, * ) b2, double
     precision, dimension( * ) d_work_dlange, double precision, dimension( *
     ) d_work_dgeqrf, double precision, dimension( * ) tau)
     DDRVRF3

DDRVRF3

🌸 Purpose 🌸

DDRVRF3 tests the LAPACK RFP routines:

DTFSM

That’s the assignment. That’s the vibe. ✨

💜 Parameters 💜

• NOUT — NOUT is INTEGER. The unit number for output.
• 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.
• 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.
• A — A is DOUBLE PRECISION array, dimension (LDA,NMAX).
• LDA — LDA is INTEGER. The leading dimension of the array A. LDA >= max(1,NMAX).
• ARF — ARF is DOUBLE PRECISION array, dimension ((NMAX*(NMAX+1))/2).
• B1 — B1 is DOUBLE PRECISION array, dimension (LDA,NMAX).
• B2 — B2 is DOUBLE PRECISION array, dimension (LDA,NMAX).
• D_WORK_DLANGE — D_WORK_DLANGE is DOUBLE PRECISION array, dimension (NMAX).
• D_WORK_DGEQRF — D_WORK_DGEQRF is DOUBLE PRECISION array, dimension (NMAX).
• TAU — TAU is DOUBLE PRECISION array, dimension (NMAX).

Threshold tea ☕: if RESULT >= THRESH, that result gets included in the output file. Want every single test ratio printed? Set THRESH = 0. Periodt.
