💖 lis_vector_set_values(3) 💖

okay bestie, this one lives in the Lis Library Functions family, so you already know it's giving serious linear-solver energy ✨

---

🌸 NAME 🌸

lis_vector_set_values — assign the scalar values to the rows of the vector 🫶

---

✨ SYNOPSIS ✨

#include "lis.h"

LIS_INT lis_vector_set_values(LIS_INT flag, LIS_INT count, LIS_INT index[], LIS_SCALAR value[], LIS_VECTOR v);

---

🦋 DESCRIPTION 🦋

So here's the vibe: you're taking value[i] and you're assigning it to the index[i]-th row of the vector v, where [i]=0,1,...,[count]-1. like, one by one, cute little scalars finding their homes 💅

---

🎀 INPUT 🎀

• flag — the mode selector, and it's giving two options bestie:
  • LIS_INS_VALUE

v[index[i]] = value[i]

straight up insert, no math, just placing it there 💖

• LIS_ADD_VALUE

v[index[i]] = v[index[i]] + value[i]

adding on top of whatever was already chilling in that row ✨

• i — The location where the value is assigned
• value — The scalar value to be assigned
• v — The destination vector (where the magic lands 🌈)

---

👑 OUTPUT 👑

• v — The vector with the scalar value assigned to the i-th row 🫶

---

💀 EXIT STATUS 💀

The following exit values are returned:

• 0 — The process is normally terminated 🎉
• unspecified — An error occurred 😭

---

🔥 NOTE 🔥

For the multiprocessing environment, the i-th row of the global vector must be specified instead of the i-th row of the partial vector. no cap, this one matters or you'll be so confused 🙈
