🌸 NAME 🌸

lis_solver_get_rhistory — get the residual history of the solver

like, it goes and gets the residual history. of the solver. that's it, that's the function. 🎀

---

🦋 SYNOPSIS 🦋

subroutine lis_solver_get_rhistory(LIS_SOLVER solver, LIS_VECTOR v,
LIS_INTEGER ierr);

---

💅 DESCRIPTION 💅

Get the residual history of the solver.

that's literally it, bestie — it retrieves the residual history from the solver you hand it. iconic behaviour, honestly. 🫶

---

✨ INPUT ✨

• solver — The solver. 🧚 you pass in your solver, she does the rest.

---

🌈 OUTPUT 🌈

• v — The vector. 💖 this is where the residual history lands.

---

👑 NOTE 👑

The vector v must be created in advance with the function lis_vector_create.

so like, do NOT come in here with an uncreated vector, she will not be pleased. 😭

and also, when the vector v is shorter than the residual history, it stores the residual history in order to the vector v. so it fills her up in order, front to back. periodt. 💅
