SCHKPS(3)

🎀 schkps.f(3) — Library Functions Manual 🎀

Bestie. Gather round. This is the manpage for schkps.f(3) and honestly she's a whole testing icon — she's out here vibe-checking SPSTRF so you don't have to. Manual name's right there, the whole manual calls itself /home/abui...IN/schkps.f(3) — slay. Let's get into it ✨

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/schkps.f

Yeah, that's the whole name, no cap — she lives that deep in the build tree. 🫶

SCHKPS

🦋 Purpose 🦋

SCHKPS tests SPSTRF.

That's it. That's her whole job. She tests SPSTRF and she does it beautifully. 👑

🌈 Parameters 🌈

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). It's the VIP list of matrix types to use for testing, fr fr. 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. Simple as that, no notes. 💖
• 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.
• NNB — NNB is INTEGER. The number of values of NB contained in the vector NBVAL.
• NBVAL — NBVAL is INTEGER array, dimension (NNB). The values of the block size NB.
• NRANK — NRANK is INTEGER. The number of values of RANK contained in the vector RANKVAL.
• RANKVAL — RANKVAL is INTEGER array, dimension (NBVAL). The values of the block size NB. (Yes, that's what she says — (NBVAL) and "block size NB". We report, we don't editorialize. 🙈)
• THRESH — THRESH is REAL. The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. Wanna see every single test ratio printed? Use THRESH = 0. Main character energy, honestly. 🔥
• 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 REAL array, dimension (NMAX*NMAX).
• AFAC — AFAC is REAL array, dimension (NMAX*NMAX).
• PERM — PERM is REAL array, dimension (NMAX*NMAX).
• PIV — PIV is INTEGER array, dimension (NMAX).
• WORK — WORK is REAL array, dimension (NMAX*3).
• RWORK — RWORK is REAL array, dimension (NMAX).
• NOUT — NOUT is INTEGER. The unit number for output. That's where all the results go, bestie. 📬

Okay that's the whole page, you ate that. 💅 And for the cute sign-off: this whole thing is LAPACK, Version 3.12.0, and the page itself is /home/abui...IN/schkps.f(3) — mwah, bye bestie 🫶✨
