💖 lis_matrix_set_coo — the Lis Library Functions era 💖

okay bestie, so you know lis_matrix_set_coo(3), right? no? well. sit down, grab a strawberry 🍓, because this little function is about to become your whole personality.

✨ NAME ✨

lis_matrix_set_coo — the one that associates the arrays in the COO format with the matrix. literally its entire job. no cap. 💅

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_matrix_set_coo(LIS_INT nnz, LIS_INT row[], LIS_INT col[],
LIS_SCALAR value[], LIS_MATRIX A);

look at that signature. gorgeous. iconic. it's giving "I know exactly what I'm doing" energy. 🦋

🎀 DESCRIPTION 🎀

So the whole vibe here is: you take the arrays in the COO format and you associate them with matrix A. that's it. that's the function. it's a matchmaker, honestly. it's setting them up. 💖

🔥 INPUT 🔥

  • nnz — the number of nonzero elements. like, how many actual numbers are doing something in there. the main characters only, bestie. 👑
  • row, col, value — the arrays in the COO format. the trio. the friend group. row says where, col says where, value says what. they don't do anything without each other, fr fr. 🫶
  • A — the matrix. the one getting all the attention. main character energy, 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, and you WILL be checking them:

  • 0 — the process is normally terminated. slay. everything worked. we love to see it. 🎉
  • unspecified — an error occurred. 💀 yeah. something went wrong. not cute. not the moment. go debug, bestie.

💜 NOTE 💜

okay this part is IMPORTANT, like actually important, so listen up: after lis_matrix_set_coo is called, the function lis_matrix_assemble must be called. like, mandatory. not optional. not "maybe later". it's the sequel. you cannot skip the sequel. 😭
