✨ SYNOPSIS ✨

🧚 Functions/Subroutines

       subroutine dchkgt (dotype, nn, nval, nns, nsval, thresh, tsterr, a, af,
           b, x, xact, work, rwork, iwork, nout)

🌸 Function/Subroutine Documentation 🌸

   subroutine dchkgt (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, double
       precision thresh, logical tsterr, double precision, dimension( * ) a,
       double precision, dimension( * ) af, double precision, dimension( * ) b,
       double precision, dimension( * ) x, double precision, dimension( * )
       xact, double precision, dimension( * ) work, double precision, dimension( * )
       rwork, integer, dimension( * ) iwork, integer nout)
       DCHKGT

And yes, the routine itself is literally called DCHKGT. No cap. 👑

🎀 Purpose 🎀

DCHKGT tests DGTTRF, -TRS, -RFS, and -CON

🧚 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.
• 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.
• A — A is DOUBLE PRECISION array, dimension (NMAX*4).
• AF — AF is DOUBLE PRECISION array, dimension (NMAX*4).
• B — B is DOUBLE PRECISION array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.
• X — X is DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• XACT — XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX).
• WORK — WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NSMAX)).
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)).
• IWORK — IWORK is INTEGER array, dimension (2*NMAX).
• NOUT — NOUT is INTEGER. The unit number for output.
