🦋 SGENND(3) 🦋

okay bestie, so this is a page from the Library Functions Manual for /home/abui...IN/sgennd.f(3) — yes it's a Fortran file living its best life inside a C-style manpage wrapper, we love a crossover moment 💅

✨ NAME ✨

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

that's the whole name, no cap — the entire long dramatic path is the name, it's giving "my full legal name on the birth certificate" energy 😭

🌸 SYNOPSIS 🌸

Functions/Subroutines

  • logical function SGENND (m, n, a, lda) — SGENND

literally that's it, that's the synopsis, she's lowkey minimal about it 🎀

💖 Function/Subroutine Documentation 💖

logical function SGENND (integer m, integer n, real, dimension( lda, * ) a, integer lda)

SGENND

🫶 Purpose:

!>
!>    SGENND tests that its argument has a non-negative diagonal.
!>

so the whole entire job of this icon is: check that the thing you handed her has a diagonal where every entry is non-negative. that's the vibe check she runs. periodt 💅

🎀 Parameters

  • M
!>          M is INTEGER
!>          The number of rows in A.
!>

it's an INTEGER and it's the number of rows in A. that's how many rows. slay.

  • N
!>          N is INTEGER
!>          The number of columns in A.
!>

also an INTEGER, and this one counts the columns in A. columns! not rows! don't mix them up bestie 🙈

  • A
!>          A is REAL array, dimension (LDA, N)
!>          The matrix.
!>

a REAL array with dimension (LDA, N), and — plot twist — it's the matrix. the main character herself 👑

  • LDA
!>          LDA is INTEGER
!>          Leading dimension of A.
!>

an INTEGER doing the leading-dimension thing for A. yes, it's that LDA. you know the one. iykyk 🔥
