lis_esolver_get_iterex(3f)

💖 lis_esolver_get_iterex — bestie, let's count those iterations 💖

okay so this is a page from the Lis Library Functions manual (yes, that Lis, the library functions one, iykyk ✨), and it's here to help you pull the receipts on your eigensolver. No cap.

✨ NAME ✨

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

Like, it literally goes and gets you the nitty-gritty deets on how many iterations that one specific eigenpair took. Obsessed. 💅

---

🎀 SYNOPSIS 🎀

subroutine lis_esolver_get_iterex(LIS_ESOLVER esolver, LIS_INTEGER *iter, LIS_INTEGER ierr);

---

🌸 DESCRIPTION 🌸

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

That's the whole vibe. You hand it an eigensolver, it hands you back the iteration tea. Periodt. 💖

---

🦋 INPUT 🦋

• esolver — The eigensolver. That's the one, bestie. The eigensolver you're interrogating. 🕵️‍♀️

---

⭐ OUTPUT ⭐

• iter — The number of iterations. The count. The whole point of the exercise. ✨
• iter_double — The number of double precision iterations. (Double the precision, double the drama. 🔥)
• iter — The number of quadruple precision iterations. 👑

👀 heads up: the original page lists iter twice — once for the number of iterations and once for the number of quadruple precision iterations — and also lists iter_double for the double precision ones. So don't come for me, I'm just reporting exactly what's on the page, fr fr. 🙈

and that's the whole page, bestie 🫶 go forth and count your iterations, you gorgeous little numerical-analysis main character 💜
