lis_vector_xpay(3)

✨ lis_vector_xpay ✨

okay bestie, gather round, because we're about to talk about the Lis Library Functions and specifically the lil icon that is lis_vector_xpay 💅

---

🌸 NAME 🌸

lis_vector_xpay — calculate the sum of the vectors

---

🎀 SYNOPSIS 🎀

#include "lis.h"

LIS_INT lis_vector_xpay(LIS_SCALAR alpha, LIS_VECTOR x, LIS_VECTOR y);

---

💖 DESCRIPTION 💖

So what this does is calculate the sum of the vectors, and it does it like this:

y = x + alpha * y

that's it. that's the whole vibe. you hand it a scalar and two vectors and it goes off. 🦋

---

🌈 INPUT 🌈

• alpha — the scalar value, i.e. the little number you're multiplying y by before the add. lowkey the flavoring of the whole operation ✨
• x, y — the vectors. yes both of them. they're a package deal, iykyk 🫶

---

👑 OUTPUT 👑

• y — it's x + alpha * y, and heads up bestie, vector y is overwritten. so like, your original y? gone. replaced. main character now. no cap 😭

---

💀 EXIT STATUS 💀

here's what it returns when it's done:

• 0 — the process is normally terminated. slay, everything went great 🎉
• unspecified — an error occurred. not the vibe. something went wrong and it's not telling us what 🙈
