lis_matrix_duplicate(3f)

lis_matrix_duplicate 💖

okay so bestie, welcome to the Lis Library Functions corner of the man pages, aka lis_matrix_duplicate(3f) — the function that's literally just "make me a twin" but for matrices. no cap. 🦋

---

✨ NAME ✨

lis_matrix_duplicate — duplicate the matrix 🫶

---

✨ SYNOPSIS ✨

subroutine lis_matrix_duplicate(MATRIX *Ain, LIS_MATRIX *Aout,
LIS_INTEGER ierr);

like. that's the whole vibe. three arguments, in and out, plus the little ierr bestie that tells you how it went. 💅

---

✨ DESCRIPTION ✨

Create matrix Aout which has the same information as Ain. 🎀

that's it, that's the function. you hand it a matrix, it hands you back a matrix that's giving the exact same information. matching energy fr fr. ✨

---

✨ INPUT ✨

• Ain — The source matrix. this is the one you're duplicating, the original, the main character 👑

---

✨ OUTPUT ✨

• Aout — The destination matrix. this is where your fresh little duplicate lands 🌸

---

✨ NOTE ✨

⚠️ bestie, read this part, i'm so serious ⚠️

The function lis_matrix_duplicate does not copy the elements of the matrix, but allocates only the memory. 😭

so like… you get the shape of a duplicate, the allocated space, the whole setup — but the actual values? not there yet. empty. a beautiful empty vessel. 🫙✨

To copy the values as well, the function lis_matrix_copy must be called after this function. so the order is: lis_matrix_duplicate first, then lis_matrix_copy. do it out of order and it's giving nothing, i fear 💀
