💖 lis_array_axpyz(3) 💖

okay bestie, welcome to the Lis Library Functions corner of the manual, where we're about to do some extremely cute vector math. this one is lis_array_axpyz and she is serving ✨ addition ✨

---

✨ NAME ✨

lis_array_axpyz — calculate the sum of the vectors 🧮💫

---

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_array_axpyz(LIS_INT n, LIS_SCALAR alpha, LIS_SCALAR x[],
LIS_SCALAR y[], LIS_SCALAR z[]);

like yes she takes five arguments and she eats every single time 💅

---

🦋 DESCRIPTION 🦋

Calculate the sum of the vectors, and the sum in question is literally this:

z = alpha * x + y

so you take vector x, you scale it by the scalar alpha, you add vector y on top, and the whole vibe lands in z. no cap, that's the entire plot 🎀

---

🌈 INPUT 🌈

• n — the size of the vectors. like, how many entries each one has, bestie 📏
• alpha — the scalar value. the little multiplier doing all the heavy lifting 💁‍♀️
• x, y — the arrays that store the vectors. the source material, the main characters 👑

---

⭐ OUTPUT ⭐

• z — alpha * x + y. that's it, that's the result, she's gorgeous 😭💖

---

🔥 EXIT STATUS 🔥

the following exit values are returned, so pay attention:

• 0 — the process is normally terminated. we love a clean exit, periodt ✨
• unspecified — an error occurred. not the vibe, but it happens 🙈

ngl if you're out here doing vector math and you didn't know about this one, now you know. iykyk 🦋
