okay bestie, welcome to the lis_array_ge page, it's giving linear algebra main character energy 💅

💖 NAME 💖

lis_array_ge — calculate the inverse of the matrix with the Gaussian elimination

no cap, that's literally the whole vibe: you hand it a matrix, it hands you back the inverse, and Gaussian elimination is doing all the heavy lifting behind the scenes 🫶

---

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_array_ge(LIS_INT n, LIS_SCALAR a[]);

---

🦋 DESCRIPTION 🦋

So here's the tea ☕ — this function calculates the inverse A^-1 of matrix A, and it does it with the Gaussian elimination. That's it, that's the function. Invert. Slay. Periodt. ✨

---

🎀 INPUT 🎀

• n — the size of the matrix, bestie. just the size. that's all she needs 🌈
• a — the array that stores matrix A of size n * n. yes, all n * n of it, she's thorough 💜

---

🍓 OUTPUT 🍓

• a — the inverse of the matrix 👑 the glow-up happened in place, the array comes back transformed fr fr

---

💀 EXIT STATUS 💀

The following exit values are returned:

• 0 — the process is normally terminated 🥳 we ate, no crumbs
• unspecified — an error occurred 😭 it's giving chaos, it's giving "something went wrong and honestly we're not gonna be specific about it"

this was lis_array_ge(3) from the Lis Library Functions set, dated 3 Dec 2014 — yeah she's vintage, she's an icon, she's been serving Gaussian elimination since 2014 and she's not stopping 🎀💖🦋

fr fr keep every flag, argument and value exactly as written — the vibe is flexible, the facts are not 💀🌸
