✨ lis_array_nrm1 — the 1-norm bestie ✨

okay so this is a page from the Lis Library Functions manual, and today's main character is lis_array_nrm1(3). it's giving math girlie, it's giving vector vibes 💅

🎀 NAME 🎀

lis_array_nrm1 — bestie, this calculates the 1-norm of the vector. that's the whole job. no cap. ✨

---

🦋 SYNOPSIS 🦋

#include "lis.h"

LIS_INT lis_array_nrm1(LIS_INT n, LIS_SCALAR x[], LIS_SCALAR *value);

like, that's the whole signature. four things. iconic behavior honestly 🫶

---

🌸 DESCRIPTION 🌸

so basically: this function calculates the 1-norm of the vector x. that's it. that's the vibe check. lowkey elegant, highkey useful. 💖

---

🍓 INPUT 🍓

• n — the size of the vector. like how many lil guys are in there 👑
• x — the array that stores the vector. the actual data, the moment, the content 🌈

---

💜 OUTPUT 💜

• value — the 1-norm of the array. this is where the answer goes, bestie, pls hand it a pointer 🙈

---

💀 EXIT STATUS 💀

here's what you might get back:

• 0 — the process is normally terminated. slay, everything went fine ✨
• unspecified — an error occurred. 😭 not the unspecified error. we don't know what happened and that's the scariest part fr fr

and that's the whole page, bestie!! this was lis_array_nrm1(3) from the Lis Library Functions, and the page footer says it was dated 3 Dec 2014 — so yeah, she's been serving accurate norm math since way before we were cool. periodt. 💅💖✨
