lis_esolver_get_iters(3)

✨ NAME ✨

lis_esolver_get_iters — get the numbers of iterations for all the eigenpairs from the eigensolver 💖

okay so real quick vibe check first: this little cutie lives in the Lis Library Functions manual, section 3 (that's the library-calls section, iykyk 🫶). And the name is not clickbait bestie, it does exactly what it says — you hand it an eigensolver, it gives you back the iteration counts for every single eigenpair. no cap, that's the whole job. 🎀

📖 SYNOPSIS 📖

#include "lis.h"

LIS_INT lis_esolver_get_iters(LIS_ESOLVER esolver, LIS_VECTOR v);

---

🌸 DESCRIPTION 🌸

Get the numbers of iterations for all the eigenpairs from the eigensolver. 🌈

that's it, that's the function. it's giving "quiet luxury" — no drama, no surprises, just the iteration counts for every eigenpair your eigensolver cooked up. obsessed. ✨

---

💅 INPUT 💅

• esolver — the eigensolver 👑 like, the one you've already been running, the main character. this is where the numbers are coming from, so obviously it has to exist first.

---

🎀 OUTPUT 🎀

• v — the vector which stores the numbers of iterations 🦋 she's the vessel bestie, she holds the receipts for every eigenpair.

---

🔥 EXIT STATUS 🔥

the following exit values are returned:

• 0 — the process is normally terminated 💖 slay, we love a clean finish.
• unspecified — an error occurred 😭 not the vibe, something went wrong somewhere.

---

🦋 NOTE 🦋

Vector v must be created in advance with the function lis_vector_create. 🚨

like, actually in advance bestie, not "I'll do it later". if v isn't already living its best life thanks to lis_vector_create, this whole thing is gonna fall apart. do not skip this step, fr fr. 🙈

and that's the whole page, bestie 💜 this one came from the Lis Library Functions manual, dated 28 Aug 2014 — yes she's an elder but she still ate. go forth and count those iterations. periodt. ✨🎀💅
