DSPNT2D(3NCARG)

💖 DSPNT2D 💖

okay bestie, welcome to DSPNT2D, a lil subroutine from the NCAR GRAPHICS manual (section 3NCARG, iykyk). it does one job and it does it gorgeously: interpolate at a single point (or a whole lil squad of points) in 2D, but make it double precision ✨

🌸 NAME 🌸

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

✨ SYNOPSIS ✨

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

🎀 DESCRIPTION 🎀

okay so here's the whole cast of characters, no skips, no skimming, we're doing this properly 🫶

• N — (Integer, Input) — The number of input data points. that's how many lil data guys you're feeding in.
• 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. That is, Z(L) is the value of the input function at coordinate (X(L),Y(L)), for L=1,N. so like… the vibes at each spot, numerically speaking 🌈
• M — (Integer, Input) — The number of output data points (this may be "1"). yes literally just one is allowed, it's giving solo mission 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 required, she's chill like that 😌
• YO — (Double precision, Input) — An array of dimension M containing the Y coordinates of the output data. The values in YO may be in any order. same energy, zero judgement.
• ZO — (Double precision, Output) — An array of dimension M containing the interpolated values. ZO(I) is the interpolated value at point (XO(I),YO(I)) for I=1,M. this is the moment, the payoff, the main character reveal 👑
• IER — (Integer, Output) — An error return value. If IER is returned as 0, then no errors were detected. If IER is non-zero, then refer to the man page for dsgrid_errors for details. so if it comes back as 0 we're thriving, and if it doesn't… go read dsgrid_errors, bestie, it has the lore 📖

💫 USAGE 💫

This subroutine is called when you want to interpolate at an individual point or points. like, one point. or several. your call, queen 🧚
