lis_esolver_get_rhistory(3)

💖 lis_esolver_get_rhistory — Lis Library Functions 💖

okay bestie, we're diving into lis_esolver_get_rhistory from the Lis Library Functions era, and honestly? it's giving "I just want my residuals and I want them now." let's get into it 🫶

---

✨ NAME ✨

lis_esolver_get_rhistory — grab the residual history for the eigenpair you asked for, straight from the eigensolver 💅

---

🌸 SYNOPSIS 🌸

#include "lis.h"

LIS_INT lis_esolver_get_rhistory(LIS_ESOLVER esolver, LIS_VECTOR v);

---

🦋 DESCRIPTION 🦋

so basically: you call this and it gets the residual history for the specified eigenpair out of the eigensolver. that's the whole vibe. no cap. ✨

---

🎀 INPUT 🎀

• esolver — the eigensolver, your main character in this situation 👑

---

🌈 OUTPUT 🌈

• v — the vector, aka where the goods land 💖

---

⭐ EXIT STATUS ⭐

here's what you might get back:

• 0 — the process is normally terminated, we love a clean exit 🥳
• unspecified — an error occurred 😭 not the vibe

---

💜 NOTE 💜

listen up, this part matters fr fr 🚨

the vector v must be created in advance with the function lis_vector_create. do not skip this step, bestie, it's not optional.

and when the vector v is shorter than the residual history? it stores the residual history in order to the vector v. so it's filling it up in sequence, one after another, periodt. 💅
