Fitgrid(3NCARG)

✨ Fitgrid ✨

okay so bestie, welcome to Fitgrid, a whole package from the NCAR GRAPHICS manual (that's the manual name btw, it lives in section 3NCARG 💅) that's all about interpolating one dimensional and two dimensional data. and when I say it does a lot, I mean it does a LOT. the package has the following functionality:

1. Interpolating single-valued functions in one dimension.
2. Interpolating parametric curves in the plane.
3. Computing an interpolatory surface through a rectangular grid of functional values.
4. Interpolating periodic functions in one dimension.
5. Finding integrals and derivatives of interpolated functions.

like??? five whole things. we love a multitasking icon 🫶

🎀 ACCESS 🎀

ngl this part is important, don't skip it 🙈 to use fitgrid entries, you load the NCAR Graphics library ngmath. that's it. that's the whole vibe check.

and that's the whole page fr fr 💅 this version of the Fitgrid(3NCARG) man page came out of the UNIX manual, dated March 1998 — yes she's an elder icon and she still ate 👑💖 bye bestie, go interpolate something gorgeous ✨🦋
