💅 Function/Subroutine Documentation 💅

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( * )

!> DCHKTZ tests DTZRZF.

🎀 Parameters 🎀

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). It picks which matrix types get 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, no notes 💅
• NM — NM is INTEGER. It’s the number of values of M contained in the vector MVAL.
• MVAL — MVAL is INTEGER array, dimension (NM). These are the values of the matrix row dimension M.
• 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 column dimension N.
• THRESH — THRESH is DOUBLE PRECISION. 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.
• 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.

okay that’s the whole page, bestie 🫶 the footer vibe is LAPACK Version 3.12.0, source /home/abui...IN/dchktz.f(3), and no date is printed in that footer — so I’m not making one up, periodt 💖
