CCHKPT(3)

💅 NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cchkpt.f — okay bestie, this is the Library Functions Manual page for CCHKPT(3), and it is giving full LAPACK test-routine energy. The shortened header path also shows up as /home/abui...IN/cchkpt.f(3), so yes, that truncated-looking path is literally part of the page. 🫶

✨ SYNOPSIS

🧩 Functions/Subroutines

   subroutine CCHKPT (dotype, nn, nval, nns, nsval, thresh, tsterr, a, d,
       e, b, x, xact, work, rwork, nout)
       CCHKPT

🌸 Function/Subroutine Documentation

   subroutine CCHKPT (logical, dimension( * ) dotype, integer nn, integer,
       dimension( * ) nval, integer nns, integer, dimension( * ) nsval, real
       thresh, logical tsterr, complex, dimension( * ) a, real, dimension( * )
       d, complex, dimension( * ) e, complex, dimension( * ) b, complex,
       dimension( * ) x, complex, dimension( * ) xact, complex, dimension( * )
       work, real, dimension( * ) rwork, integer nout)

And the name, once more with feeling: CCHKPT. Main character energy, honestly. 👑

🎯 Purpose

The purpose is exactly this: CCHKPT tests CPTTRF, -TRS, -RFS, and -CON.

That’s the whole purpose block. No extra lore, no side quest. 💅

💅 Parameters

• DOTYPE — a LOGICAL array, dimension (NTYPES). These are 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. No plus-one, no invite. 🙈
• NN — NN is INTEGER: the number of values of N contained in the vector NVAL. 🎀
• NVAL — NVAL is an INTEGER array, dimension (NN): the values of the matrix dimension N. ✨
• NNS — NNS is INTEGER: the number of values of NRHS contained in the vector NSVAL. 🦋
• NSVAL — NSVAL is an INTEGER array, dimension (NNS): the values of the number of right hand sides NRHS. 🌸
• THRESH — THRESH is REAL: 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 a COMPLEX array, dimension (NMAX*2). 💜
• D — D is a REAL array, dimension (NMAX*2). 🍓
• E — E is a COMPLEX array, dimension (NMAX*2). 🌈
• B — B is a COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL. ⭐
• X — X is a COMPLEX array, dimension (NMAX*NSMAX). 💖
• XACT — XACT is a COMPLEX array, dimension (NMAX*NSMAX). 🔥
• WORK — WORK is a COMPLEX array, dimension (NMAX*max(3,NSMAX)). 🧚
• RWORK — RWORK is a REAL array, dimension (max(NMAX,2*NSMAX)). 😭
• NOUT — NOUT is INTEGER: the unit number for output. 👑

Okay bestie, that’s the whole CCHKPT(3) page. Footer sign-off tea: LAPACK, Version 3.12.0, source path /home/abui...IN/cchkpt.f(3) — and there’s no separate date printed on this footer, so that’s the entire date situation. Slay. 💖✨
