/home/abui...G/cblat2.f(3)

💖 NAME 💖

So this page is from the Library Functions Manual, section 3, and the thing it's documenting is a whole file path, bestie:

/home/abuild/rpmbuild/BUILD/lapack-
static-3.12.0-build/lapack-3.12.0/BLAS/TESTING/cblat2.f

Yep. That's the entire NAME stanza. It's literally just the file's whole life story as a path — cblat2.f living its best life inside the BLAS TESTING directory of the lapack-static-3.12.0-build rpmbuild tree. No cap, that's the name. 🫶

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

Okay so this is the part where I list every single function and subroutine this file has to offer — and I mean every one, no skipping, no "and friends", we're doing all of them 💅. Signatures are copied exactly, character for character, because we do not play with argument lists. 🌸

program CBLAT2 — the program itself, main character energy fr fr 👑
- CBLAT2 — yep, that's the name again, it's a whole program and it's called CBLAT2
subroutine CCHK1 — a subroutine, and here is its full arg list, exactly as written: (sname, eps, thresh, nout, ntra, trace, rewi, fatal, nidim, idim, nkb, kb, nalf, alf, nbet, bet, ninc, inc, nmax, incmax, a, aa, as, x, xx, xs, y, yy, ys, yt, g) 🦋
subroutine CCHK2 — another one, and look at that arg list, it's giving long: (sname, eps, thresh, nout, ntra, trace, rewi, fatal, nidim, idim, nkb, kb, nalf, alf, nbet, bet, ninc, inc, nmax, incmax, a, aa, as, x, xx, xs, y, yy, ys, yt, g) ✨
subroutine CCHK3 — this one swaps in xt and z, obsessed: (sname, eps, thresh, nout, ntra, trace, rewi, fatal, nidim, idim, nkb, kb, ninc, inc, nmax, incmax, a, aa, as, x, xx, xs, xt, g, z) 🎀
subroutine CCHK4 — no kb/bet here, but it's got z at the end, periodt: (sname, eps, thresh, nout, ntra, trace, rewi, fatal, nidim, idim, nalf, alf, ninc, inc, nmax, incmax, a, aa, as, x, xx, xs, y, yy, ys, yt, g, z) 💜
subroutine CCHK5 — same energy, same exact arg list as its sibling, lowkey iconic: (sname, eps, thresh, nout, ntra, trace, rewi, fatal, nidim, idim, nalf, alf, ninc, inc, nmax, incmax, a, aa, as, x, xx, xs, y, yy, ys, yt, g, z) 🌈
subroutine CCHK6 — and the sixth one, same args again, the way they just kept the pattern: (sname, eps, thresh, nout, ntra, trace, rewi, fatal, nidim, idim, nalf, alf, ninc, inc, nmax, incmax, a, aa, as, x, xx, xs, y, yy, ys, yt, g, z) 🌸
subroutine CCHKE — short and sweet, only three args: (isnum, srnamt, nout) 🧚
subroutine CMAKE — a builder-ish little guy, here's the whole thing: (type, uplo, diag, m, n, a, nmax, aa, lda, kl, ku, reset, transl) 🔥
subroutine CMVCH — big arg list incoming, brace yourself: (trans, m, n, alpha, a, nmax, x, incx, beta, y, incy, yt, g, yy, eps, err, fatal, nout, mv) 😭
logical function LCE — note: it returns a logical, bestie, and it takes (ri, rj, lr) 🦋
logical function LCERES — also a logical function: (type, uplo, m, n, aa, as, lda) ✨
complex function CBEG — this one returns complex and takes exactly one thing: (reset) 💀
real function SDIFF — returns real, takes two: (x, y) ⭐
subroutine CHKXER — args: (srnamt, infot, nout, lerr, ok) 🌈
subroutine CREGR1 — long boi, all of it, no edits: (trans, m, n, ly, kl, ku, alpha, a, lda, x, incx, beta, y, incy, ys) 🎀
subroutine XERBLA — the classic, taking (srname, info) 👑

That's every single entry in the synopsis, bestie — nothing dropped, nothing merged, nothing "cleaned up" 💖

✨ Function/Subroutine Documentation ✨

okay bestie, buckle up — this is the part where the page just... lists everything. Every single routine in cblat2.f, signature and all. No descriptions for most of them (the source is lowkey mysterious like that 🙈), but we are NOT skipping any, because every detail matters. 💅

🌸 `CBEG`

complex function CBEG (logical reset)

(that's it. that's the whole entry. she's giving mystery, she's giving "look me up in the source" energy ✨)

👑 program `CBLAT2`

🎀 Purpose:

fr fr this is the main character of the whole file, so listen up:

Test program for the COMPLEX Level 2 Blas.

The program must be driven by a short data file. The first 18 records of the file are read using list-directed input, and the last 17 records are read using the format ( A6, L2 ). An annotated example of a data file can be obtained by deleting the first 3 characters from the following 35 lines — and here they are, verbatim, don't touch anything:

!> 'cblat2.out'      NAME OF SUMMARY OUTPUT FILE
!> 6                 UNIT NUMBER OF SUMMARY FILE
!> 'CBLA2T.SNAP'     NAME OF SNAPSHOT OUTPUT FILE
!> -1                UNIT NUMBER OF SNAPSHOT FILE (NOT USED IF .LT. 0)
!> F        LOGICAL FLAG, T TO REWIND SNAPSHOT FILE AFTER EACH RECORD.
!> F        LOGICAL FLAG, T TO STOP ON FAILURES.
!> T        LOGICAL FLAG, T TO TEST ERROR EXITS.
!> 16.0     THRESHOLD VALUE OF TEST RATIO

notice how CCHK3 has xt and z instead of y/yt/yy/ys — she's built different, and yes that's just how it is 💅

okay so CCHK4, CCHK5 and CCHK6 look near-identical but CCHK6's z is dimension( nmax, 2 ) — two columns, because she needs room for two vectors. not me noticing that on the third read 😭
