💖 lis_matrix_set_csr — bestie edition 💖

okay so this is a page from the Lis Library Functions manual, section 3, and it's all about lis_matrix_set_csr ✨

---

🌸 NAME 🌸

lis_matrix_set_csr — it associates the arrays in the CSR format with the matrix 🫶

---

✨ SYNOPSIS ✨

#include "lis.h"

LIS_INT lis_matrix_set_csr(LIS_INT nnz, LIS_INT ptr[], LIS_INT index[],
LIS_SCALAR value[], LIS_MATRIX A);

---

💅 DESCRIPTION 💅

So basically you're taking your arrays in the CSR format and gluing them onto matrix A. That's it, that's the whole vibe 💖

---

🎀 INPUT 🎀

• nnz — the number of nonzero elements 🔢
• ptr, index, value — the arrays in the CSR format 👑 (yes, all three, they're a package deal)
• A — the matrix 🦋

---

🍓 OUTPUT 🍓

• A — the matrix, now associated with the arrays. glow up complete ✨

---

💀 EXIT STATUS 💀

here's what you can get back:

• 0 — the process is normally terminated, slay 💅
• unspecified — an error occurred 😭 (no further info, it's giving mystery)

---

🌈 NOTE 🌈

okay this is important bestie, do NOT forget: after lis_matrix_set_csr is called, the function lis_matrix_assemble must be called. like, must. no skipping. periodt 💜
