CCHKSP(3)

💅 CCHKSP(3) — like, the LAPACK testing queen arrives

okay bestie, so this page is from the LAPACK manual (section 3, library functions), and the file it lives in is literally:

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

yes that whole entire path is the NAME. it's giving "my full government name" energy 😭 but that's literally what it is, no cap.

✨ SYNOPSIS ✨

Functions/Subroutines 🫶

subroutine CCHKSP (dotype, nn, nval, nns, nsval, thresh, tsterr, nmax,
    a, afac, ainv, b, x, xact, work, rwork, iwork, nout)

CCHKSP — that's the icon, that's the main character 👑

CCHKSP

Purpose: 💖

CCHKSP tests CSPTRF, -TRI, -TRS, -RFS, and -CON

like, it's the vibe-checker for five whole routines. it puts them through it. periodt. 🔥

🌸 Parameters 🌸

• DOTYPE

DOTYPE is LOGICAL array, dimension (NTYPES) 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.

it's the guest list bestie 💅 type j is either invited (.TRUE.) or not (.FALSE.), simple as.

• NN

NN is INTEGER The number of values of N contained in the vector NVAL.

how many N's we bringing to the party.

• NVAL

NVAL is INTEGER array, dimension (NN) The values of the matrix dimension N.

the actual N values themselves. the sizes. the lewks. ✨

• NNS

NNS is INTEGER The number of values of NRHS contained in the vector NSVAL.

same deal but for right-hand sides, iykyk.

• NSVAL

NSVAL is INTEGER array, dimension (NNS) The values of the number of right hand sides NRHS.

all the NRHS values, lined up and ready.

• 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.

so like, if you're nosy and want everything printed, set it to 0. full transparency slay 🔍

• TSTERR

TSTERR is LOGICAL Flag that indicates whether error exits are to be tested.

are we testing the error paths too? yes or no, that's the flag.

• NMAX

NMAX is INTEGER The maximum value permitted for N, used in dimensioning the work arrays.

the ceiling. the limit. used to size the work arrays so nothing overflows 🙈

• A

A is COMPLEX array, dimension (NMAX*(NMAX+1)/2)

• AFAC

AFAC is COMPLEX array, dimension (NMAX*(NMAX+1)/2)

• AINV

AINV is COMPLEX array, dimension (NMAX*(NMAX+1)/2)

• B

B is COMPLEX array, dimension (NMAX*NSMAX) where NSMAX is the largest entry in NSVAL.

ok note that NSMAX detail — it's the biggest value in NSVAL, not a variable you pass. got it? 🫶

• X

X is COMPLEX array, dimension (NMAX*NSMAX)

• XACT

XACT is COMPLEX array, dimension (NMAX*NSMAX)

• WORK

WORK is COMPLEX array, dimension (NMAX*max(2,NSMAX))

yes max(2,NSMAX) — two is the floor, she never goes lower 💀

• RWORK

RWORK is REAL array, dimension (NMAX+2*NSMAX)

• IWORK

IWORK is INTEGER array, dimension (NMAX)

• NOUT

NOUT is INTEGER The unit number for output.

~ cute lil sign-off ~ 🦋

this whole glow-up is brought to you by LAPACK, Version 3.12.0, and the page's own little footer stamp: /home/abui...IN/cchksp.f(3). mwah 💋 go test those routines bestie, you got this 🫶💖
