lis_matrix_get_size(3)

💖 lis_matrix_get_size(3) 💖

okay bestie, so this one is from the Lis Library Functions manual and it's literally the cutest lil utility — it just tells you how big your matrix is. no cap. that's the whole vibe. 🦋

---

✨ NAME ✨

lis_matrix_get_size — get the size of the matrix 👑

---

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_matrix_get_size(LIS_MATRIX A, LIS_INT *local_n, LIS_INT *global_n);

---

💅 DESCRIPTION 💅

Get the size of matrix A. that's it. that's the function. she's simple, she's iconic, she serves. 🎀

---

🫶 INPUT 🫶

• A — the matrix, obviously. your main character matrix. the one you're measuring. 📏

---

🌈 OUTPUT 🌈

• local_n — the size of the partial matrix (iykyk — this is the chunk of the matrix that this process is holding onto 💖)
• global_n — the size of the global matrix (the whole entire thing, the full picture, the big picture energy ✨)

---

💀 EXIT STATUS 💀

here's what you can get back, bestie:

• 0 — the process is normally terminated. slay. everything worked. 🥳
• unspecified — an error occurred. not slay. 😭

---

⭐ NOTE ⭐

important lore: in the case of the serial and multithreaded environments, local_n is equal to global_n. so like... they're the same number. twins. matching. no difference at all. don't overthink it. 💜
