💅 ztsqr01.f — Library Functions Manual (yes bestie, we're in the Fortran section)

okay so picture this: you're deep in the LAPACK testing directory (/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/ztsqr01.f — say that five times fast, I dare you 🫶) and you find this little icon. It's a library function page, it's giving academic but make it cute, and honestly? We're obsessed.

✨ SYNOPSIS ✨

Functions/Subroutines

  • subroutine ZTSQR01 (tssw, m, n, mb, nb, result) — the whole entire vibe of this page, no cap.
subroutine ZTSQR01 (character tssw, integer m, integer n, integer mb,
    integer nb, double precision, dimension(6) result)

Yeah. ZTSQR01. That's her name, that's her brand 💅

🦋 Function/Subroutine Documentation 🦋

subroutine ZTSQR01

bestie, here's the whole squad of arguments, laid out:

subroutine ZTSQR01 (character tssw, integer m, integer n, integer mb,
    integer nb, double precision, dimension(6) result)

Literally the main character. Let's get into it 💖

🎀 Purpose 🎀

ZTSQR01 tests ZGEQR , ZGELQ, ZGEMLQ and ZGEMQR.

That's it, that's the job. She's a tester — four routines walk in, she puts them through the vibe check. Slay 🔥

🌸 Parameters 🌸

TSSW

TSSW is CHARACTER 'TS' for testing tall skinny QR and anything else for testing short wide LQ

so real — if you pass 'TS' you're on tall skinny QR duty, and literally anything else means we're doing short wide LQ instead. Choose your fighter 💀

M

M is INTEGER Number of rows in test matrix.

how many rows we're working with, periodt.

N

N is INTEGER Number of columns in test matrix.

and how many columns. the other half of the duo 👑

MB

MB is INTEGER Number of row in row block in test matrix.

the row block size — number of rows per row block in the test matrix. block it up ✨

NB

NB is INTEGER Number of columns in column block test matrix.

the column block size — number of columns in the column block test matrix. matching energy 🎀

RESULT

RESULT is DOUBLE PRECISION array, dimension (6) Results of each of the six tests below.

Six slots, six tests, six receipts. Here's the lineup — copy these exactly, they're literally the result definitions:

RESULT(1) = | A - Q R | or | A - L Q | RESULT(2) = | I - Q^H Q | or | I - Q Q^H | RESULT(3) = | Q C - Q C | RESULT(4) = | Q^H C - Q^H C | RESULT(5) = | C Q - C Q | RESULT(6) = | C Q^H - C Q^H |

six little numbers, six little vibe checks. iykyk 🧚
