ZCHKPP(3)

💅 NAME 💅

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

okay bestie, this is the zchkpp.f(3) page from the Library Functions Manual — manual name folded in right here, no copy-paste of that top header line, periodt 💖

✨ Purpose ✨

!>
!> ZCHKPP tests ZPPTRF, -TRI, -TRS, -RFS, and -CON
!>

like, it is literally the vibe check for ZPPTRF, -TRI, -TRS, -RFS, and -CON 🔥

🎀 Parameters 🎀

• DOTYPE — DOTYPE is a LOGICAL array, dimension (NTYPES). This is the matrix-type guest list: matrices of type j (for 1 <= j <= NTYPES) get tested when DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. no invite, no testing 💅
• 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 dimension N ✨
• NNS — NNS is INTEGER. It’s the number of values of NRHS contained in the vector NSVAL 🦋
• NSVAL — NSVAL is INTEGER array, dimension (NNS). These are the values of the number of right hand sides NRHS 🎀
• 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 COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2) ⭐
• AFAC — AFAC is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2) 💖
• AINV — AINV is COMPLEX*16 array, dimension (NMAX*(NMAX+1)/2) 🌈
• B — B is COMPLEX*16 array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL 🍓
• X — X is COMPLEX*16 array, dimension (NMAX*NSMAX) 🦋
• XACT — XACT is COMPLEX*16 array, dimension (NMAX*NSMAX) ✨
• WORK — WORK is COMPLEX*16 array, dimension (NMAX*max(3,NSMAX)) 🔥
• RWORK — RWORK is DOUBLE PRECISION array, dimension (max(NMAX,2*NSMAX)) 🌸
• NOUT — NOUT is INTEGER. It’s the unit number for output 💅

okay that’s the whole zchkpp.f(3) moment 💫 — LAPACK Version 3.12.0, footer source path /home/abui...IN/zchkpp.f(3), and the footer didn’t show a date, so I’m not making one up, periodt 🫶💅
