NNPNTINITD(3NCARG)

✨ NAME ✨

NNPNTINITD — the glow-up era of your data: enter single point mode, but make it double precision 💅

🦋 SYNOPSIS 🦋

CALL NNPNTINITD (NPNTS, X, Y, Z)

💖 DESCRIPTION 💖

okay so here's the cast of characters you're handing over, bestie — read them carefully because this is a Fortran CALL, she is not playing around:

• NPNTS (Integer, Input) — the number of input data points. And no, two isn't gonna cut it: NPNTS > 3. fr fr, more than three. 🌸
• X (Double precision, Input) — an array of dimension NPNTS holding the X coordinates of your input data points. 🦋
• Y (Double precision, Input) — an array of dimension NPNTS holding the Y coordinates of your input data points. 🦋
• Z (Double precision, Input) — an array of dimension NPNTS holding the functional values of your input data points. So like, Z(L) is the value of the input function at coordinate (X(L),Y(L)), for L=1,NPNTS. it's giving "every point gets its moment" 💫

🎀 USAGE 🎀

you call this subroutine when you wanna interpolate at individual points. she's an initialization routine, which means she sets up some internal variables and does the initial triangulation — the whole backstage prep before the main character walks out. 👑

lowkey important: NNPNTINITD does NOT do the interpolation for you. she just sets the stage.

to actually do the interpolation, use subroutine NNPNTD. 🫶

to terminate single point mode when you're done, use the subroutine NNPNTENDD. say bye properly, it's polite. 💖

🌈 ACCESS 🌈

to use NNPNTINITD, load the NCAR Graphics library ngmath. that's the vibe check you gotta pass first. ✨
