DSPNT2D(3NCARG)

💖 DSPNT2D 💖

okay so bestie, welcome to the NCARG manual page for DSPNT2D — yes that's the one, from the NCAR Graphics corner of the universe, and no it is not a drill. 🦋

✨ NAME ✨

DSPNT2D — interpolate at a single point (or points) in 2D, in double precision 💅

Like. She does interpolation. At one point. Or many points. In TWO D. And she does it in double precision, because she's that girl. 👑

---

✨ SYNOPSIS ✨

CALL DSPNT2D (N, X, Y, Z, M, XO, YO, ZO, IER)

That's the whole vibe. Nine arguments. She's a Fortran CALL, she's uppercase, she's iconic. 🎀

---

✨ DESCRIPTION ✨

Okay so here's the tea on every single one of these arguments, and I mean every one, no skips, no skimming, we are reading the whole group chat 🫶

• N — (Integer, Input) — the number of input data points. Literally how many points you're feeding her. 🌸
• X — (Double precision, Input) — an array containing the X coordinates of the input data points. 📍
• Y — (Double precision, Input) — an array containing the Y coordinates of the input data points. 📍
• Z — (Double precision, Input) — an array containing the functional values of the input data points. So like, Z(L) is the value of the input function at coordinate (X(L),Y(L)), for L=1,N. She's mapping each point to its value, periodt. ⭐
• M — (Integer, Input) — the number of output data points. And yes bestie, this may be "1". One (1). Single. Solo. Main character energy. 💅
• XO — (Double precision, Input) — an array of dimension M containing the X coordinates of the output data. The values in XO may be in any order. No sorting, no lining up, no being normal about it. 🙈
• YO — (Double precision, Input) — an array of dimension M containing the Y coordinates of the output data. Same deal: the values in YO may be in any order. Chaos is welcome here. 💜
• ZO — (Double precision, Output) — an array of dimension M containing the interpolated values. So ZO(I) is the interpolated value at point (XO(I),YO(I)) for I=1,M. This is the payoff. This is the moment. ✨
• IER — (Integer, Output) — an error return value. If IER comes back as 0, then no errors were detected — slay, we love a clean run. 🌈 If IER is non-zero, then refer to the man page for dsgrid_errors for details. Go read that one, she has the receipts. 😭

✨ USAGE ✨

You call this subroutine when you want to interpolate at an individual point or points. That's it. That's the whole use case. One point, or a bunch of points, she doesn't mind. 🧚

---

✨ ACCESS ✨

To use DSPNT2D, load the NCAR Graphics library ngmath. Gotta have the right library loaded or she simply will not show up. 💀

and that's the whole page, no cap. she's a UNIX man page from September 1997-1998, DSPNT2D(3NCARG) in the building, and she ate. 💖✨🎀 bye bestie, go interpolate something 🌸🦋💅
