TESTING/LIN/cdrvsp.f(3)

This is the manual page for TESTING/LIN/cdrvsp.f, from the Library Functions Manual — yes, the whole page is about one subroutine and it's lowkey iconic. 💅

💖 NAME

TESTING/LIN/cdrvsp.f — that's the page, bestie. The star of the show is CDRVSP, the test-driver subroutine. ✨

✨ SYNOPSIS

Functions/Subroutines

subroutine cdrvsp (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a,
    afac, ainv, b, x, xact, work, rwork, iwork, nout)
    CDRVSP

🦋 Function/Subroutine Documentation

Here's the full signature with all the types and dimensions laid out, no cap: 🫶

subroutine cdrvsp (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, real thresh, logical tsterr, integer
    nmax, complex, dimension( * ) a, complex, dimension( * ) afac, complex,
    dimension( * ) ainv, complex, dimension( * ) b, complex, dimension( * )
    x, complex, dimension( * ) xact, complex, dimension( * ) work, real,
    dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)
    CDRVSP

🎀 Purpose

CDRVSP tests the driver routines CSPSV and -SVX. That's the whole purpose, periodt. No cap. 💖

🌸 Parameters

Every parameter, every dimension, every vibe — all here. 🫶

DOTYPE

DOTYPE is a LOGICAL array, dimension (NTYPES). It's the matrix-type guest list: for type j (where 1 <= j <= NTYPES), matrix type j is used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. Slay.

NN

NN is INTEGER. It's the number of values of N contained in the vector NVAL.

NVAL

NVAL is INTEGER array, dimension (NN). These are the values of the matrix dimension N.

NRHS

NRHS is INTEGER. It's the number of right hand side vectors to be generated for each linear system.

THRESH

THRESH is REAL. It's 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.

NMAX

NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.

A

A is COMPLEX array, dimension (NMAX*(NMAX+1)/2).

AFAC

AFAC is COMPLEX array, dimension (NMAX*(NMAX+1)/2).

AINV

AINV is COMPLEX array, dimension (NMAX*(NMAX+1)/2).

B

B is COMPLEX array, dimension (NMAX*NRHS).

X

X is COMPLEX array, dimension (NMAX*NRHS).

XACT

XACT is COMPLEX array, dimension (NMAX*NRHS).

WORK

WORK is COMPLEX array, dimension (NMAX*max(2,NRHS)).

RWORK

RWORK is REAL array, dimension (NMAX+2*NRHS).

IWORK

IWORK is INTEGER array, dimension (NMAX).

NOUT

NOUT is INTEGER. The unit number for output.
