okay so bestie, this is /home/abui...G/zblat2.f(3). The manual name is Library Functions Manual / /home/abui...G/zblat2.f(3), and the whole thing is living under lapack-static-3.12.0-build / lapack-3.12.0 energy. No cap, we're reading the BLAS testing file page. πŸ¦‹

πŸŽ€ NAME πŸŽ€

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/TESTING/zblat2.f

That's the whole NAME section, bestie. Just the path. Literally one line and it ate. πŸ’…


✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

okay so the original does not give little descriptions for these, so I'm not inventing any. Here is every function and subroutine signature, exactly as written, in one sacred code block. Do not touch the spelling, the spacing, the commas, or the arguments β€” this is the whole squad and we respect the code. 🫢

       program ZBLAT2
           ZBLAT2
       subroutine ZCHK1 (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 ZCHK2 (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 ZCHK3 (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 ZCHK4 (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 ZCHK5 (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 ZCHK6 (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 ZCHKE (isnum, srnamt, nout)
       subroutine ZMAKE (type, uplo, diag, m, n, a, nmax, aa, lda, kl, ku,
           reset, transl)
       subroutine ZMVCH (trans, m, n, alpha, a, nmax, x, incx, beta, y, incy,
           yt, g, yy, eps, err, fatal, nout, mv)
       logical function LZE (ri, rj, lr)
       logical function LZERES (type, uplo, m, n, aa, as, lda)
       complex *16 function ZBEG (reset)
       double precision function DDIFF (x, y)
       subroutine CHKXER (srnamt, infot, nout, lerr, ok)
       subroutine ZREGR1 (trans, m, n, ly, kl, ku, alpha, a, lda, x, incx,
           beta, y, incy, ys)
       subroutine XERBLA (srname, info)

Every single one from the original is in that block β€” no skips, no merges, no invented options. The names stay exactly as they are, and the arguments stay exactly where they belong. 🌈

πŸ‘‘ Program ZBLAT2

The entry is:

program ZBLAT2

And the name it shows is literally ZBLAT2.

Purpose πŸ’œ

It’s the test program for the COMPLEX*16 Level 2 Blas, no cap.

The program must be driven by a short data file. The first 18 records of the file are read using list-directed input, 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:

!> 'zblat2.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
!> 6                 NUMBER OF VALUES OF N
!> 0 1 2 3 5 9       VALUES OF N
!> 4                 NUMBER OF VALUES OF K
!> 0 1 2 4           VALUES OF K
!> 4                 NUMBER OF VALUES OF INCX AND INCY
!> 1 2 -1 -2         VALUES OF INCX AND INCY
!> 3                 NUMBER OF VALUES OF ALPHA
!> (0.0,0.0) (1.0,0.0) (0.7,-0.9)       VALUES OF ALPHA
