c_dspnt2d(3NCARG)

💖 NAME 💖

c_dspnt2d — the girl who interpolates at a single point (or a whole lil squad of points) in 2D, in single precision ✨

🧚 FUNCTION PROTOTYPE 🧚

void c_dspnt2d(int, double [], double [], double [],
               int, double [], double [], double *, int *);

🌸 SYNOPSIS 🌸

void c_dspnt2d (int n, double x[], double y[], double z[],
                int m, double xo[], double yo[], double zo, int *ier);

✨ DESCRIPTION ✨

okay bestie, here's the cast of characters 👑

• n — the number of input data points. like, how many lil guys you're feeding her.
• x — an array holding the X coordinates of your input data points.
• y — an array holding the Y coordinates of your input data points.
• z — an array holding the functional values of the input data points. so basically z[l] is the value of the input function at coordinate (x[l],y[l]), for 0 <= l < n. periodt 💅
• m — the number of output data points (and yes, this may be "1" — she can absolutely serve a party of one 🥳).
• xo — an array of dimension m holding the X coordinates of the output data. the values in xo may be in any order. no cap, any order, she does not care 🌈
• yo — an array of dimension m holding the Y coordinates of the output data. (the original really does say the values in xo may be in any order here too — not me noticing that 😭 just relaying the facts fr fr)
• zo — a pointer to a double. space for m doubles gets allocated for zo by dspnt2d. and zo[i] is the interpolated value at point (xo[i],yo[i]) for 0 <= i < n. (yep, it says n right there in the source — we are reporting, not editing 🫶)
• ier — the error return value. if *ier comes back as 0, then no errors were detected, we love a clean run ✨. if *ier is non-zero, then go refer to the man page for dsgrid_errors — that's where the tea is ☕

🎀 USAGE 🎀

you call this function when you want to interpolate 2D data at an individual point, or at a bunch of points. lowkey iconic that it handles both 💖

---

🌟 ACCESS 🌟

to use c_dspnt2d, load the NCAR Graphics library ngmath. that's the whole vibe check ✅

bestie this is c_dspnt2d from the 3NCARG manual, the NCAR GRAPHICS collection, dated September 1997-1998 on a UNIX system — and that's the whole page, go interpolate something gorgeous 💅💖✨
