lis_matrix_set_csc(3)

💖 lis_matrix_set_csc(3) 💖

okay bestie, welcome to the Lis Library Functions corner of the manual — this one's called lis_matrix_set_csc, and it's lowkey the moment where you hand your matrix a whole CSC-format glow-up. Let's get into it. 🦋

---

✨ NAME ✨

lis_matrix_set_csc — associate the arrays in the CSC format with the matrix

Like… you've got arrays. You've got a matrix. This function is the matchmaker. 💅

---

🌸 SYNOPSIS 🌸

#include "lis.h"

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

That's the whole vibe right there. Copy it exactly, no editing, we don't freestyle signatures in this house. 🎀

---

🧚 DESCRIPTION 🧚

Associate the arrays in the CSC format with matrix A.

That's it. That's the whole thing. You bring the arrays, it links them up to A, iconic behavior, no notes. ✨

---

🌈 INPUT 🌈

• nnz — the number of nonzero elements. Yes it matters, don't skip it, it's literally the headcount of your nonzeros. 🔢
• ptr, index, value — the arrays in the CSC format. The whole trio, together, as a set. 🫶
• A — the matrix. The main character, honestly. 👑

---

💜 OUTPUT 💜

• A — the matrix, now associated with the arrays. She's been matched. She's thriving. 🌟

---

🔥 EXIT STATUS 🔥

The following exit values are returned:

• 0 — the process is normally terminated. We love a clean exit. slay. 💖
• unspecified — an error occurred. 😭 not the unspecified error, she's giving mystery, she's giving chaos.

---

💀 NOTE 💀

After lis_matrix_set_csc is called, the function lis_matrix_assemble must be called.

No like fr fr, must. You can't just set and dip. This is a two-step situation, bestie, and step two is not optional. 🚨
