lis_array_mgs(3)

✨ lis_array_mgs ✨

okay bestie, so this is a page from the Lis Library Functions manual, and it's all about lis_array_mgs — the girl whose whole job is QR factorization via the modified Gram-Schmidt process 🎀

---

🌸 NAME 🌸

lis_array_mgs — calculate the QR factorization with the modified Gram-Schmidt process

---

💅 SYNOPSIS 💅

#include "lis.h"

LIS_INT lis_array_mgs(LIS_INT n, LIS_SCALAR a[], LIS_SCALAR q[],
LIS_SCALAR r[]);

---

🦋 DESCRIPTION 🦋

So basically she calculates the QR factorization QR=A with the modified Gram-Schmidt process. That's it, that's the vibe. Iconic, honestly. ✨

---

🍓 INPUT 🍓

• n — the size of the matrices, no cap
• a — the array that stores matrix A of size n * n

---

💜 OUTPUT 💜

• q — the array that stores matrix Q of size n * n
• r — the array that stores matrix R of size n * n

---

🌈 EXIT STATUS 🌈

the following exit values are returned, so listen up:

• 0 — the process is normally terminated 🫶 (we love a clean exit)
• unspecified — an error occurred 😭 (not the vibe, but okay, it happens)

lowkey if you're doing QR factorization, this is the function to call, fr fr 💯

and that's a wrap, bestie 💖 that was lis_array_mgs(3) from the Lis Library Functions manual, dated 3 Dec 2014 — the page literally just says Man Page down at the bottom, so that's the whole credit roll. go slay some matrices for me 👑✨
