TESTING/LIN/sgennd.f(3)

💖 TESTING/LIN/sgennd.f 💖

So bestie, let me tell you about this absolute icon of a file — it's part of the LAPACK library, and it's from the TESTING/LIN directory, and honestly? It's giving "unsung hero of linear algebra testing." You're gonna love it, I promise. 🎀

✨ SYNOPSIS ✨

Okay so here's the lineup of functions and subroutines in this file:

logical function sgennd (m, n, a, lda)

Literally what it says on the tin — SGENND is the main character here. Main character energy fr fr. 👑

🌸 Function/Subroutine Documentation 🌸

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

So this is the full signature — SGENND herself. Let's get into the deets:

Purpose:

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

Okay so the whole vibe of this function is: it checks whether the diagonal of the matrix you gave it is non-negative. That's it. That's the whole job. And honestly? We respect the focus. No cap. ✨

💅 Parameters 💅

Let's go through every single one, because we don't skip anything in this house:

• M — this is an INTEGER. It's the number of rows in A. That's it bestie, no mystery.

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

• N — INTEGER, still. The number of columns in A. Slay, keeping it symmetrical. 🦋

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

• A — this one's a REAL array, dimension (LDA, N). It's the matrix itself. The star of the show, the moment, the whole reason we're here. 🌟

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

• LDA — INTEGER. It's the leading dimension of A. Keeping that stride looking right, you know how it is. 💅

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

🌈 Author (the meta one) 🌈

So this whole page? Generated automatically by Doxygen for LAPACK from the source code. Very demure, very automated, very much not hand-typed by a human. We love an efficient workflow. 🧚

🎀 cute lil sign-off 🎀

Okay bestie, that's the whole page! You just read about LAPACK, Version 3.12.0, and this iconic TESTING/LIN/sgennd.f(3) page. Go forth and test those non-negative diagonals, and remember — you ate and left no crumbs. 💖✨🔥
