HPL_dlaswp10N(3)

💖 HPL_dlaswp10N 💖

okay bestie, welcome to the HPL Library Functions manual, section 3 🎀 — yes we are deep in the linear-algebra trenches and honestly? it's giving main character energy 💅

---

✨ NAME ✨

HPL_dlaswp10N — performs a series column interchanges. 🦋

---

🌸 SYNOPSIS 🌸

#include "hpl.h"

void HPL_dlaswp10N( const int M, const int N, double * A, const int LDA,
const int * IPIV );

---

💫 DESCRIPTION 💫

HPL_dlaswp10N performs a sequence of local column interchanges on a matrix A. One column interchange is initiated for columns 0 through N-1 of A. 🔥

like... it's literally just swapping columns around, one by one, for every column from 0 up to N-1. no cap. ✨

👑 ARGUMENTS 👑

okay so heads up bestie — the argument blurbs on this page are kinda scrambled in the original (the descriptions are shifted down by one slot and one of them is a literal placeholder). we're keeping it 100% verbatim because the vibe changes but the facts do not. 🙈

• M (local input) — const int
  • the page says: __arg0__ — yep, that's literally it, that's what's printed, we're not making it up 💀
• N (local input) — const int
  • "On entry, M specifies the number of rows of the array A. M must be at least zero."
• A (local input/output) — double *
  • "On entry, N specifies the number of columns of the array A. N must be at least zero."
• LDA (local input) — const int
  • "On entry, A points to an array of dimension (LDA,N). This array contains the columns onto which the interchanges should be applied. On exit, A contains the permuted matrix."
• IPIV (local input) — const int *
  • "On entry, LDA specifies the leading dimension of the array A. LDA must be at least MAX(1,M)."

🫶 bestie please read the argument names and the blurbs side by side — the source page has them slid down a slot, and one slot is the raw __arg0__ placeholder. we did not rewrite, reorder, or "fix" any of it. what you see is what the page says, fr fr. 💜
