lis_vector_nrm2(3)

💖 lis_vector_nrm2 — from the Lis Library Functions manual, bestie 💖

okay so picture this: you've got a vector. a whole vector. and you're sitting there like "bestie… how big is this thing, like actually?" that's literally the whole job of this function. it's lis_vector_nrm2, and it pulls the 2-norm out of your vector like it's nothing. no cap.

✨ NAME ✨

lis_vector_nrm2 — calculate the 2-norm of the vector 🌸

---

🎀 SYNOPSIS 🎀

#include "lis.h"

LIS_INT lis_vector_nrm2(LIS_VECTOR x, LIS_REAL *value);

---

🦋 DESCRIPTION 🦋

Calculate the 2-norm of vector x.

that's it. that's the gig. hand it your vector, it hands you back the 2-norm. iconic behavior honestly. 💅

---

🌈 INPUT 🌈

• x — The vector. your main character. the one we're measuring. 👑

---

🍓 OUTPUT 🍓

• value — The 2-norm of the vector. the number you came here for. slay. ✨

💀 EXIT STATUS 💀

The following exit values are returned:

• 0 — The process is normally terminated 🫶 (we love a clean exit, fr fr)
• unspecified — An error occurred 😭 (not the vibe, ngl)

lowkey the whole thing is just "give vector, get norm" and honestly? that's the energy. don't overthink it, bestie. 🧚
