Csagrid(3NCARG)

💖 Csagrid — NCAR GRAPHICS 💖

okay bestie, welcome to csagrid, the third-section NCAR Graphics page for the cubic spline approximation era of your life. no cap, this one's a whole package. 🌈

---

✨ NAME ✨

csagrid — cubic spline approximation. that's it, that's the vibe. 💅

---

🦋 DESCRIPTION 🦋

so Csagrid is a software package living inside the ngmath library, and what it does is implement a cubic spline approximation algorithm to fit a function to input data. main character behaviour, honestly. 👑

the input for the approximation is a set of randomly-spaced data. and here's the slay: those data may be one-dimensional, two-dimensional, or three-dimensional. pick your fighter. 🎀

the output is a set of values at coordinates on a user-specified grid, or at a set of user-specified points — and yes, that includes at a single point. one point! tiny but mighty. 🫶

functionally equivalent Fortran, C, and NCL interfaces are provided. so no matter which language you're texting from, you're covered. ✨

and for the lore girlies: Csagrid is based on the work of David Fulker and his package Splpack. we love a credited icon. 💖

and that's the page, bestie. this was the UNIX flavour of the Csagrid(3NCARG) manual, dated January 1999, straight from NCAR GRAPHICS. go fit a function to some randomly-spaced data, you absolute icon. 💖✨🎀
