TESTING/LIN/sdrvpox.f(3)

NAME

TESTING/LIN/sdrvpox.f is the Library Functions Manual page for the sdrvpo subroutine — also known as SDRVPOX. 💖

SYNOPSIS

Functions/Subroutines

subroutine sdrvpo (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, asav, b, bsav, x, xact, s, work, rwork, iwork, nout)

SDRVPOX — that’s the one, bestie. 💅

Function/Subroutine Documentation

Full signature, exactly as the source gives it:

subroutine sdrvpo (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
    nmax, real, dimension( * ) a, real, dimension( * ) afac, real,
    dimension( * ) asav, real, dimension( * ) b, real, dimension( * ) bsav,
    real, dimension( * ) x, real, dimension( * ) xact, real, dimension( * )
    s, real, dimension( * ) work, real, dimension( * ) rwork, integer,
    dimension( * ) iwork, integer nout)

SDRVPOX 🦋

Purpose

Okay so the source says: SDRVPO tests the driver routines SPOSV, -SVX, and -SVXX. 💅

Heads-up from the original: this file is used only when the XBLAS are available; otherwise sdrvpo.f defines this subroutine. No cap. 🫶

Parameters

DOTYPE

DOTYPE is a LOGICAL array with dimension (NTYPES). It’s the matrix-type guest list: for 1 <= j <= NTYPES, matrix type j is tested when DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. 🎀

NN

NN is INTEGER: how many values of N are contained in the vector NVAL. ✨

NVAL

NVAL is an INTEGER array with dimension (NN); these are 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. Want every single test ratio printed? Use THRESH = 0. 👑

TSTERR

TSTERR is LOGICAL: flag indicating 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 a REAL array with dimension (NMAX*NMAX). 🍓

AFAC

AFAC is a REAL array with dimension (NMAX*NMAX). 🍓

ASAV

ASAV is a REAL array with dimension (NMAX*NMAX). 🍓

B

B is a REAL array with dimension (NMAX*NRHS). 💜

BSAV

BSAV is a REAL array with dimension (NMAX*NRHS). 💜

X

X is a REAL array with dimension (NMAX*NRHS). 💜

XACT

XACT is a REAL array with dimension (NMAX*NRHS). 💜

S

S is a REAL array with dimension (NMAX). 🌈

WORK

WORK is a REAL array with dimension (NMAX*max(3,NRHS)). ⭐

RWORK

RWORK is a REAL array with dimension (NMAX+2*NRHS). ⭐

IWORK

IWORK is an INTEGER array with dimension (NMAX). 🌸

NOUT

NOUT is INTEGER: the unit number for output. 🎀
