💖 NNPNTINITS — bestie, we're entering single point mode 💖

okay so this is a page from the NCAR Graphics manual, 3NCARG section, and it's all about a Fortran subroutine called NNPNTINITS. Strap in, it's giving ✨initialization✨ and honestly? iconic.

✨ SYNOPSIS ✨

CALL NNPNTINITS (NPNTS, X, Y, Z)

🌸 DESCRIPTION 🌸

Here's the tea on the arguments, bestie — four of them, all input, no cap:

  • NPNTS — Integer, Input. The number of input data points. And listen, it's gotta be NPNTS > 3. Like, more than three, fr fr. Don't test it. 🫶
  • X — Real, Input. An array of dimension NPNTS holding the X coordinates of your input data points.
  • Y — Real, Input. An array of dimension NPNTS holding the Y coordinates of your input data points.
  • Z — Real, Input. An array of dimension NPNTS holding the functional values of your input data points. So basically Z(L) is the value of the input function at the coordinate (X(L),Y(L)), for L=1,NPNTS. She's mapping, she's serving coordinates, periodt. 💅

🦋 USAGE 🦋

So when do you even call this thing? You call it when you want to interpolate at individual points. That's the whole vibe. 💖

It's an initialization routine — it sets up some internal variables and does the initial triangulation. The way it just sets things up for you... main character energy honestly. 👑

But lowkey important: this is just the setup. To actually do the interpolation, you use subroutine NNPNTS. And to terminate single point mode when you're done? That's subroutine NNPNTEND. Don't just ghost it, bestie, close the loop. 🎀

🌈 ACCESS 🌈

Wanna use NNPNTINITS? You gotta load the NCAR Graphics library ngmath. That's the whole thing. Load it up and slay. ✨
