💖 NNPNTD — bestie's guide to interpolating one single point (double precision edition) 💖

okay so this is NNPNTD, from the NCAR Graphics crew, living in the 3NCARG section of the manual. It's the double-precision twin of the single-point interpolation vibe. Let's go 🦋

✨ SYNOPSIS ✨

CALL NNPNTD (X, Y, Z)

that's it. that's the whole call. three arguments, one little point, no cap 💅

🌸 DESCRIPTION 🌸

here's the tea on each argument, no skipping:

  • X — (Double precision, Input) — the X coordinate of the point where you want that interpolation, bestie. the exact spot. 🎯
  • Y — (Double precision, Input) — the Y coordinate of the point where interpolation is desired. the other half of your little coordinate moment. 🎯
  • Z — (Double precision, Output) — the interpolated functional value at the point (X,Y). this is what you came for. this is the gift. 🎁

🫶 USAGE 🫶

so you call this subroutine when you want to interpolate at one individual point. just one. a single point. she's main character energy and she doesn't share the spotlight.

⚠️ but listen — NNPNTINITD must be called before you call NNPNTD, and NNPNTENDD must be called to terminate single point mode. don't skip your setup and don't skip your cleanup, i'm literally begging 🙈 the order is not optional, it's giving choreography.

🎀 ACCESS 🎀

to use NNPNTD, load the NCAR Graphics library ngmath. that's the whole access situation. load the lib, live your truth. ⭐
