lis_esolver_get_iterex(3)

✨ lis_esolver_get_iterex ✨

okay bestie, so this one is from the Lis Library Functions manual, section 3 — it's lis_esolver_get_iterex(3) and it's literally just about peeking at how many iterations your eigensolver did for a specific eigenpair. no cap. 💅

---

🌸 NAME 🌸

lis_esolver_get_iterex — get the detailed information on the number of iterations for the specified eigenpair from the eigensolver 🦋

---

💖 SYNOPSIS 💖

#include "lis.h"

LIS_INT lis_esolver_get_iterex(LIS_ESOLVER esolver, LIS_INT *iter);

like, that's the whole vibe. include the header, call the function, boom. ✨

---

🎀 DESCRIPTION 🎀

Get the detailed information on the number of iterations for the specified eigenpair from the eigensolver.

that's it, that's the whole thing. you hand it your eigensolver and a pointer, and it tells you how many iterations went into the eigenpair you care about. it's giving "receipts for your solver's effort" energy fr fr 👑

---

🌈 INPUT 🌈

• esolver — the eigensolver. yes queen, this is the one you're interrogating 💅

---

🍓 OUTPUT 🍓

• iter — the number of iterations
• iter_double — the number of double precision iterations
• iter — the number of quadruple precision iterations

not me noticing iter shows up twice in this list 🙈 that's literally how the original page has it, so i'm keeping it exactly as-is. no edits, no "fixes", we respect the source in this house 💖

---

⭐ EXIT STATUS ⭐

the following exit values are returned:

1. 0 — the process is normally terminated 🥳
2. unspecified — an error occurred 😭

so like, 0 is the slay outcome, and unspecified is the "something went wrong and honestly we're not gonna elaborate" outcome. lowkey ominous but okay 💀

that's the whole page bestie, hope your iterations are plentiful and your exit status is 0 💜

sending you off with the classic footer energy: this one's from the Lis Library Functions manual, dated 28 Aug 2014 — yes, it's been iconic for a minute 🎀✨
