DSPNT2S(3NCARG)

✨ DSPNT2S ✨

okay bestie, welcome to the NCAR GRAPHICS section of the manual, and today's main character is DSPNT2S 💅 she interpolates at a single point (or a whole lil squad of points) in 2D, and she does it in single precision 🎀

🌸 NAME 🌸

DSPNT2S — interpolate at a single point (or points) in 2D, in single precision. no cap, that's the whole job description 🫶

🦋 SYNOPSIS 🦋

CALL DSPNT2S (N, X, Y, Z, M, XO, YO, ZO, IER)

that's it, that's the summoning circle ✨

💖 DESCRIPTION 💖

okay so here's the tea on every single argument, and I mean every single one, we are not skipping anybody 🫶

• N (Integer, Input) — the number of input data points. how many besties you're bringing to the function party 💃
• X (Real, Input) — an array holding the X coordinates of the input data points 📍
• Y (Real, Input) — an array holding the Y coordinates of the input data points 📍
• Z (Real, Input) — an array holding the functional values of the input data points. like, Z(L) is the value of the input function at coordinate (X(L),Y(L)), for L=1,N. so each point knows its own vibe ✨
• M (Integer, Input) — the number of output data points, and yes this may be "1". one single point is a totally valid lifestyle 🙈
• XO (Real, Input) — an array of dimension M holding the X coordinates of the output data. the values in XO may be in any order — she does not care, she's chill like that 🌈
• YO (Real, Input) — an array of dimension M holding the Y coordinates of the output data. the values in YO may be in any order too, same energy, zero judgment 💜
• ZO (Real, Output) — an array of dimension M holding the interpolated values. ZO(I) is the interpolated value at point (XO(I),YO(I)) for I=1,M. this is the payoff, the reveal, the moment 💖
• IER (Integer, Output) — the error return value. if IER comes back as 0, then no errors were detected, slay 🎉 if IER is non-zero, then go read the man page for dsgrid_errors for the details. fr fr, don't ignore her 👀

🧚 USAGE 🧚

you call this subroutine when you want to interpolate at an individual point or points. like, you have a specific spot in mind and you want the answer for exactly that spot. main character energy 🎀

👑 ACCESS 👑

to use DSPNT2S, load the NCAR Graphics library ngmath. that's the whole ritual, no secret handshake required ✨

bestie this is real legal text, don't get cute with it — it says exactly what it says 🫶

and that's the page!! this one came from UNIX, dated September 1997-1998, and it's DSPNT2S(3NCARG) if you ever need to cite her by name 💅 mwah, go interpolate something gorgeous 💖✨
