lis_solve(3)

✨ lis_solve(3) — bestie we're SOLVING today ✨

okay so real talk, this is a page from the Lis Library Functions manual, and it's about lis_solve, and honestly? she's the whole point of the library. the main character. the reason we're all here. 🫶

---

🌸 NAME 🌸

lis_solve — solve the linear equation 💅

---

🎀 SYNOPSIS 🎀

#include "lis.h"

LIS_INT lis_solve(LIS_MATRIX A, LIS_VECTOR b, LIS_VECTOR x, LIS_SOLVER solver);

that's it. four args. hand it your stuff and she goes. ✨

---

🦋 DESCRIPTION 🦋

Solve the linear equation with the specified solver.

like. that's literally what it does. you bring the matrix, the right hand side, a starting guess, and the solver you picked out, and lis_solve just... does the thing. no cap. 🔥

---

💖 INPUT 💖

the stuff you gotta hand her:

• A — The coefficient matrix. the big one. the whole vibe. 🧚
• b — The right hand side vector.
• x — The initial vector. your little starting guess, bestie.
• solver — The solver. the one you set up. the chosen one. 👑

---

🌈 OUTPUT 🌈

the stuff she hands back:

• x — The solution. THE solution. the moment we've all been waiting for. 😭💜
• solver — The number of iterations, the execution time, etc. she fills in the receipts so you can see how hard she worked. ⭐

---

💀 EXIT STATUS 💀

The following exit values are returned:

• 0 — The process is normally terminated. slay. everything ate. 🎉
• unspecified — An error occurred. not the vibe check we wanted, bestie. 🙈

ngl if you get anything that isn't 0, that's your sign something went sideways. "unspecified" is doing a lot of heavy lifting in that sentence but she said what she said.
