TESTING/LIN/zchkps.f(3)

okay bestie, welcome to the TESTING/LIN/zchkps.f(3) page from the Library Functions Manual — literally the zchkps zone, and it's giving LAPACK test-routine energy. 💅

🌸 NAME 🌸

TESTING/LIN/zchkps.f — the page for the zchkps test routine. It tests ZPSTRF, no cap. ✨

---

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

subroutine zchkps (dotype, nn, nval, nnb, nbval, nrank, rankval, thresh,
           tsterr, nmax, a, afac, perm, piv, work, rwork, nout)
           ZCHKPS

🦋 Function/Subroutine Documentation 🦋

here's the full signature, copied exactly because we do not play with code:

subroutine zchkps (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nnb, integer, dimension( * ) nbval, integer
       nrank, integer, dimension( * ) rankval, double precision thresh, logical
       tsterr, integer nmax, complex*16, dimension( * ) a, complex*16,
       dimension( * ) afac, complex*16, dimension( * ) perm, integer,
       dimension( * ) piv, complex*16, dimension( * ) work, double precision,
       dimension( * ) rwork, integer nout)
       ZCHKPS

🎀 Purpose 🎀

ZCHKPS tests ZPSTRF. that's the whole purpose, and it ate. 💖

👑 Parameters 👑

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). it's the matrix-type menu: matrices of type j (for 1 <= j <= NTYPES) get used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. ✨
• NN — NN is INTEGER. it's the number of values of N contained in the vector NVAL. 🎀
• NVAL — NVAL is an INTEGER array, dimension (NN). these are the values of the matrix dimension N. 💅
• NNB — NNB is INTEGER. it's the number of values of NB contained in the vector NBVAL. 🦋
• NBVAL — NBVAL is an INTEGER array, dimension (NNB). these are the values of the block size NB. 🌸
• NRANK — NRANK is INTEGER. it's the number of values of RANK contained in the vector RANKVAL. 🫶
• RANKVAL — RANKVAL is an INTEGER array, dimension (NBVAL). and the page literally says: the values of the block size NB. (yes bestie, that's what it says 😭). keep it exactly like that.
• 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. it's the flag that indicates whether error exits are to be tested. 💀
• NMAX — NMAX is INTEGER. it's the maximum value permitted for N, used in dimensioning the work arrays. 👑
• A — A is a COMPLEX*16 array, dimension (NMAX*NMAX). 🌈
• AFAC — AFAC is a COMPLEX*16 array, dimension (NMAX*NMAX). ⭐
• PERM — PERM is a COMPLEX*16 array, dimension (NMAX*NMAX). 💜
• PIV — PIV is an INTEGER array, dimension (NMAX). 🍓
• WORK — WORK is a COMPLEX*16 array, dimension (NMAX*3). 🧚
• RWORK — RWORK is a DOUBLE PRECISION array, dimension (NMAX). 🙈
• NOUT — NOUT is INTEGER. it's the unit number for output. 💖

🎀 that's the whole page, bestie! footer vibes: LAPACK, Version 3.12.0, page TESTING/LIN/zchkps.f(3) — and that's the sign-off. periodt. 💅✨
