✨ lis_matrix_axpyz — calculate the sum of the matrices ✨

okay bestie, welcome to lis_matrix_axpyz(3), one of the lil gems from the Lis Library Functions manual 💖 she does one thing and she does it gorgeously: adds matrices together. that's it. that's the whole vibe. and honestly? obsessed. 🎀

---

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_matrix_axpyz(LIS_SCALAR alpha, LIS_MATRIX A, LIS_MATRIX B,
LIS_MATRIX C);

like, look at that signature. so clean. so structured. the way she takes a scalar and three matrices and just delivers 🫶

---

💅 DESCRIPTION 💅

Calculate the sum of the matrices C = alpha * A + B.

that's literally the whole thing, and it's giving math major main character energy fr fr. you hand her a scalar, you hand her two matrices, and she hands you back a third matrix that's the sum. no cap ✨

---

🌈 INPUT 🌈

• alpha — the scalar value 🍓 (yes bestie, she gets multiplied across everything, that's her job)
• A, B — the matrices 💜 the two cuties going into the blender

---

👑 OUTPUT 👑

• C — alpha * A + B 💫 the glow-up result, freshly computed and ready for you

---

💀 EXIT STATUS 💀

the following exit values are returned, and yes you should lowkey check them:

• 0 — the process is normally terminated 🌸 everything slayed, nothing broke, we love to see it
• unspecified — an error occurred 😭 something went sideways, and she's not gonna tell you exactly what, which is... a choice

---

🎀 NOTE 🎀

Matrices A, B and C must be in the DNS format. like, this is not optional, bestie. not a suggestion. not a vibe. if they're not in DNS format, do not pass go, do not collect your sum. 💅
