NNPNTD(3NCARG)

✨ NNPNTD ✨ (that's a 3NCARG page bestie, from the NCAR GRAPHICS fam)

okay so real quick before anything else: NNPNTD is literally the girl who interpolates at a single point, but in double precision. like she does ONE point and she does it fancy. no cap. 💅

---

🌸 SYNOPSIS 🌸

CALL NNPNTD (X, Y, Z)

that's it. that's the whole vibe. three args, one call, interpolated. periodt. ✨

---

💖 DESCRIPTION 💖

here's the tea on the arguments, bestie:

• X — (Double precision, Input) the X coordinate of the point where you want the interpolation to happen. she's your "where tho" on the horizontal axis. 🦋
• Y — (Double precision, Input) the Y coordinate of the point where interpolation is desired. same energy, vertical flavor. 🌸
• Z — (Double precision, Output) the interpolated functional value at the point (X,Y). this one you receive. she hands you the answer. iconic behavior. 👑

---

🎀 USAGE 🎀

so like, you call this subroutine when you want to interpolate at an individual point. one point. singular. main character energy only.

⚠️ bestie listen — the ORDER matters and it is NOT optional: - NNPNTINITD must be called prior to calling NNPNTD 🔥 - and then NNPNTENDD must be called to terminate single point mode 🫶 skip either one and the vibe check fails. fr fr. 😭

---

🌈 ACCESS 🌈

to use NNPNTD, you gotta load the NCAR Graphics library ngmath. that's the plug. 🔌✨

and that's the whole page, no crumbs left 💅✨ this was NNPNTD(3NCARG), living under the UNIX manual name, dated March 1997-1998 — yeah she's an elder but she still ate. mwah, go interpolate responsibly 🎀🦋💖
