Hey bestie 💖 this is the manual page for TESTING/LIN/dchktz.f — yes, from the Library Functions Manual, the TESTING/LIN/dchktz.f(3) girlie herself. Let's get into it.

💅 Function/Subroutine Documentation 💅

Okay so here's the full signature, bestie — character for character, no cap:

   subroutine dchktz (logical, dimension( * ) dotype, integer nm, integer,
       dimension( * ) mval, integer nn, integer, dimension( * ) nval, double
       precision thresh, logical tsterr, double precision, dimension( * ) a,
       double precision, dimension( * ) copya, double precision, dimension( * )
       s, double precision, dimension( * ) tau, double precision, dimension( *
       ) work, integer nout)

DCHKTZ

🎀 Purpose 🎀

okay so DCHKTZ tests DTZRZF. That is literally the purpose — periodt. 💅

🍓 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. iconic behavior, honestly.

💜 NM

NM is INTEGER. The number of values of M contained in the vector MVAL.

💜 MVAL

MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M.

💜 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 column 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. slay.

💜 TSTERR

TSTERR is LOGICAL. Flag that indicates whether error exits are to be tested.

💜 A

A is DOUBLE PRECISION array, dimension (MMAX*NMAX) where MMAX is the maximum value of M in MVAL and NMAX is the maximum value of N in NVAL.

💜 COPYA

COPYA is DOUBLE PRECISION array, dimension (MMAX*NMAX).

💜 S

S is DOUBLE PRECISION array, dimension (min(MMAX,NMAX)).

💜 TAU

TAU is DOUBLE PRECISION array, dimension (MMAX).

💜 WORK

WORK is DOUBLE PRECISION array, dimension (MMAX*NMAX + 4*NMAX + MMAX).

💜 NOUT

NOUT is INTEGER. The unit number for output.
