NNPNTINITS(3NCARG)

💖 NNPNTINITS 💖 — enter single point mode (yes bestie, it's giving NCAR Graphics)

okay so hi!! you found the page for NNPNTINITS, a lil Fortran subroutine from the NCAR GRAPHICS world (that's the manual, 3NCARG, iykyk). short version: it flips you into single point mode. it's the setup girlie, not the one who does the actual work — she just gets everything ready so the real ones can shine. ✨

🌸 SYNOPSIS 🌸

CALL NNPNTINITS (NPNTS, X, Y, Z)

that's it. four arguments. she's lowkey simple, highkey essential. 🫶

---

🎀 DESCRIPTION 🎀

here's the tea on every single argument, no skips, no skips, fr fr:

• NPNTS — (Integer, Input) — the number of input data points. and babes, heads up: (NPNTS > 3). like, strictly greater than 3. three is not the vibe here. 🚫
• X — (Real, Input) — an array of dimension NPNTS holding the X coordinates of the input data points. the horizontal situation. 💅
• Y — (Real, Input) — an array of dimension NPNTS holding the Y coordinates of the input data points. the vertical situation. together with X she's serving coordinates. 📍
• Z — (Real, Input) — an array of dimension NPNTS holding the functional values of the input data points. translation bestie: Z(L) is the value of the input function at coordinate (X(L),Y(L)), for L=1,NPNTS. so every point gets a lil value on top. iconic. 👑

✨ USAGE ✨

so when do you even call this?? call it when you wanna interpolate at individual points. she's an initialization routine — she sets up some internal variables and does this initial triangulation. that's the whole job. she's the opening act. 🎤

then, to actually do the interpolation?? use the subroutine NNPNTS. she's the main character. 🌟

and when you're done and you wanna bounce out of single point mode?? use the subroutine NNPNTEND. close the door behind you, queen. 🚪💨

lowkey important: NNPNTINITS ≠ interpolation. she's prep work. don't @ me, that's just what the page says. 🙈

🌈 ACCESS 🌈

to use NNPNTINITS, you gotta load the NCAR Graphics library ngmath. that's the whole access situation. go get her. 🏃‍♀️
