CDRVPT(3)

🎀 CDRVPT(3) — the lapack testing tea 🎀

okay so bestie, this page is from the LAPACK library functions manual, and the file it lives in is literally /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cdrvpt.f 💅 like yes the whole path, we're not hiding it.

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/cdrvpt.f — that's the whole name, no cap, it's giving "my parents named me after the street they met on" 😭

🌸 SYNOPSIS 🌸

Functions/Subroutines

• subroutine CDRVPT (dotype, nn, nval, nrhs, thresh, tsterr, a, d, e, b, x, xact, work, rwork, nout) — CDRVPT

---

🦋 Function/Subroutine Documentation 🦋

subroutine CDRVPT (logical, dimension( * ) dotype, integer nn, integer,
    dimension( * ) nval, integer nrhs, 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)

CDRVPT ✨

💖 Purpose 💖

!>
!> CDRVPT tests CPTSV and -SVX.
!>

so it's literally a test driver for CPTSV and -SVX, that's the whole vibe check 🫶

👑 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: matrix type j (for 1 <= j <= NTYPES) gets in only if DOTYPE(j) = .TRUE. — if it's .FALSE. then type j is not used, periodt 🙅‍♀️

• NN

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

an INTEGER, the number of N values chillin' inside NVAL 💜

• NVAL

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

INTEGER array, dimension (NN), holding the matrix dimension N values ✨

• NRHS

!>          NRHS is INTEGER
!>          The number of right hand side vectors to be generated for
!>          each linear system.
!>

an INTEGER, how many right hand side vectors get generated for each linear system, lowkey the whole squad of RHS vectors 🌈

• 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.
!>

a REAL, the threshold for the test ratios — a result makes it into the output file if RESULT >= THRESH. want every test ratio printed? use THRESH = 0, easy 💅

• TSTERR

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

a LOGICAL flag: are we testing error exits or not, that's the question 🎀

• A

!>          A is COMPLEX array, dimension (NMAX*2)
!>

COMPLEX array, dimension (NMAX*2) ⭐

• D

!>          D is REAL array, dimension (NMAX*2)
!>

REAL array, dimension (NMAX*2) ⭐

• E

!>          E is COMPLEX array, dimension (NMAX*2)
!>

COMPLEX array, dimension (NMAX*2) ⭐

• B

!>          B is COMPLEX array, dimension (NMAX*NRHS)
!>

COMPLEX array, dimension (NMAX*NRHS) ⭐

• X

!>          X is COMPLEX array, dimension (NMAX*NRHS)
!>

COMPLEX array, dimension (NMAX*NRHS) ⭐

• XACT

!>          XACT is COMPLEX array, dimension (NMAX*NRHS)
!>

COMPLEX array, dimension (NMAX*NRHS) ⭐

• WORK

!>          WORK is COMPLEX array, dimension
!>                      (NMAX*max(3,NRHS))
!>

COMPLEX array, dimension (NMAX*max(3,NRHS)) — note the max(3,NRHS) bestie, it's doing the most 🧚

• RWORK

!>          RWORK is REAL array, dimension (NMAX+2*NRHS)
!>

REAL array, dimension (NMAX+2*NRHS) ⭐

• NOUT

!>          NOUT is INTEGER
!>          The unit number for output.
!>

an INTEGER, the unit number for output, aka where all the gossip gets printed 💖
