💖 NAME 💖

lis_esolver_get_evectors — okay bestie, this one grabs all the eigenvectors from the eigensolver. All of them. The whole squad. 👑

(also it lives in the Lis Library Functions family, and its manual page is lis_esolver_get_evectors(3f), iykyk)

✨ SYNOPSIS ✨

subroutine lis_esolver_get_evectors(LIS_ESOLVER esolver, LIS_MATRIX A,
LIS_INTEGER ierr);

Look at that signature, she's giving structured. 🎀

🌸 DESCRIPTION 🌸

So like. You've got an eigensolver, right? And it's been doing its little eigensolver thing, computing away, being all mysterious 🧚. This routine is the moment where you go "okay hand over the eigenvectors" and it does. It gets all the eigenvectors from the eigensolver. Every single one. No crumbs left behind. 💅

---

🦋 INPUT 🦋

• esolver — the eigensolver. That's her. That's the whole input. Give her the eigensolver and she knows what to do. ✨

---

💜 OUTPUT 💜

• v — the matrix in the COO format which stores the eigenvectors. That's where all the eigenvectors end up, chillin' in COO format, waiting for you. 🫶

---

🎀 NOTE 🎀

Matrix A must be created in advance with the function lis_matrix_create. Do not come in here with an uncreated matrix, bestie, that is not the vibe. Create first, then call. Periodt. 💀
