lis_vector_get_value(3f)

💖 lis_vector_get_value(3f) — the Lis Library Functions era 💖

okay bestie, so this is a page from the Lis Library Functions manual, section 3f, and it's all about one lil' subroutine that goes and fetches you a single scalar value out of a vector. yes. one number. that's the whole gig. and honestly? iconic behavior. 🎀

---

✨ NAME ✨

lis_vector_get_value — get the value of the row of the vector 🦋

like, it gets the value of the row of the vector. that's literally what it does. no notes. 💅

---

✨ SYNOPSIS ✨

subroutine lis_vector_get_value(LIS_INTEGER flag, LIS_INTEGER i,
LIS_SCALAR value, LIS_VECTOR v, LIS_INTEGER ierr);

she takes five arguments and she does not take any nonsense. periodt. ✨

---

✨ DESCRIPTION ✨

Get the scalar value of the i-th row of the vector.

that's it. that's the plot. you point at a vector, you say "gimme row number i", and you get back the scalar sitting there. main character energy for a one-liner, honestly. 💜

---

✨ INPUT ✨

• i — the location where the value is assigned 📍 like, this is you telling her where to look, bestie.
• v — the source vector 🌸 the actual vector you're pulling from. the source of truth. the moment.

---

✨ OUTPUT ✨

• value — the value of the i-th row 🫶 so this is the thing you came for, the lil' scalar she hands back to you. it's giving gift. it's giving present.

---

✨ NOTE ✨

⚠️ okay so this one matters, fr fr — for the multiprocessing environment, the i-th row of the global vector must be specified. don't come at her with some local-index nonsense and then act surprised. she said GLOBAL. 💀

okay and for the cute sign-off: this whole thing came out of the Lis Library Functions manual, and the page itself is dated 6 Sep 2012 — yeah, she's an elder but she ate and left no crumbs. 💅✨ bye bestie, go get your values 🦋💖
