lis_array_solve(3)

💖 lis_array_solve — bestie we are SOLVING today 💖

okay so real talk, this is a page from the Lis Library Functions manual, and it's literally just lis_array_solve being the main character. she solves linear equations the direct way, no iterative drama, no cap. let's get into it 🫶

✨ NAME ✨

lis_array_solve — solve the linear equation with the direct method 💅

---

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_array_solve(LIS_INT n, LIS_SCALAR a[], LIS_SCALAR b[],
LIS_SCALAR x[], LIS_SCALAR w[]);

---

🦋 DESCRIPTION 🦋

so basically she solves the linear equation Ax=b with the direct method. that's it. that's the whole vibe. no iterative guessing games, she just goes straight for it. iconic behavior honestly 👑

🎀 INPUT 🎀

here's what you gotta hand her, bestie. don't forget any of these or it's giving error 😭

• n — the size of the matrix. the whole squad size, lowkey.
• a — the array that stores coefficient matrix A of size n * n. she's big, she's square, she's the moment.
• b — the array that stores right hand side vector b of size n.
• w — the work array w of size n * n. this is her little backstage area, her prep room, she needs it to cook 🍓

---

⭐ OUTPUT ⭐

• x — the array that stores solution x. the answer!! the payoff!! she ate and left no crumbs 🔥

---

🌈 EXIT STATUS 🌈

the following exit values are returned, so pay attention bestie:

• 0 — the process is normally terminated. slay, everything worked, we're thriving 💜
• unspecified — an error occurred. not the vibe. something went wrong and we don't know exactly what. tragic fr fr 💀
