TESTING/LIN/zchksp.f(3)

💅 NAME

This is the TESTING/LIN/zchksp.f(3) page in the Library Functions Manual — manual name folded in like a little bow, bestie. 🎀 And the actual name here? TESTING/LIN/zchksp.f — yes, that's the icon. 💖

🎀 SYNOPSIS

🧚 Functions/Subroutines

       subroutine zchksp (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax,
           a, afac, ainv, b, x, xact, work, rwork, iwork, nout)
           ZCHKSP

🦋 Function/Subroutine Documentation

   subroutine zchksp (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, logical tsterr, integer nmax, complex*16, dimension( *
       ) a, complex*16, dimension( * ) afac, complex*16, dimension( * ) ainv,
       complex*16, dimension( * ) b, complex*16, dimension( * ) x, complex*16,
       dimension( * ) xact, complex*16, dimension( * ) work, double precision,
       dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)

ZCHKSP — that's the routine, and it's giving main character energy. 👑

✨ Purpose

Okay so ZCHKSP tests ZSPTRF, -TRI, -TRS, -RFS, and -CON. That's literally the whole purpose, no cap. 💅

🍓 Parameters

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). These are the matrix types used for testing. For type j where 1 <= j <= NTYPES, it gets used for testing when 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.
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL.
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS.
• 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.
• NMAX — NMAX is INTEGER. The maximum value permitted for N, used in dimensioning the work arrays.
• A — A is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2).
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX).
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX).
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(2,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NSMAX).
• IWORK — IWORK is INTEGER array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. 🖨️
