lis_array_axpy(3)

💖 lis_array_axpy — bestie edition 💖

okay so we're in the Lis Library Functions corner of the manual, section 3, and today's main character is lis_array_axpy(3). she does one thing and she does it gorgeously, no cap.

---

✨ NAME ✨

lis_array_axpy — calculate the sum of the vectors 🫶

---

🌸 SYNOPSIS 🌸

#include "lis.h"

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

---

🦋 DESCRIPTION 🦋

bestie. listen. this function calculates the sum of the vectors, and the way it does it is literally:

y = alpha * x + y

that's it. that's the whole vibe. alpha times x, plus y, and the answer lands right back in y. iconic behaviour, honestly. 🎀

---

🍓 INPUT 🍓

• n — the size of the vectors. like, how many numbers are we working with, bestie.
• alpha — the scalar value. she's the multiplier, she's the moment. 💅
• x, y — the arrays that store the vectors. the two girlies doing all the work.

---

👑 OUTPUT 👑

• y — this is where alpha * x + y goes. heads up though: vector y is overwritten. she doesn't get a copy, she gets a glow-up in place. 🙈

---

💀 EXIT STATUS 💀

the following exit values are returned, and yes we're checking them like the responsible queens we are:

• 0 — the process is normally terminated. slay. ✨
• unspecified — an error occurred. not the vibe. 😭
