💖 GBINTERP(1) 💖

okay bestie, so this is the manual page for gbinterp, a lil User Command that lives in your terminal and does one thing and does it gorgeously. it's giving ✨interpolation era✨ and honestly? we're obsessed. it's version 6.2, June 2021, and yes, she's an icon. let's get into it 🫶

🌸 NAME 🌸

gbinterp — Compute equispaced curve from interpolated

(that's the whole name line, no notes, she's concise and she's correct 💅)

🎀 SYNOPSIS 🎀

gbinterp [options]

literally that's it. just vibes and options. no positional args, no chaos, no cap ✨

🦋 DESCRIPTION 🦋

So here's the tea, bestie 💖: gbinterp computes the interpolating function of the data you provide, and it does it on a regular mesh. very demure, very regular.

  • Data get read from standard input as couples (X,Y). two numbers per line, that's the whole assignment.
  • The interpolation (x, f(x)) gets printed for x in [rmin,rmax]. so you hand it a range, it hands you back the interpolated curve, slay.
  • If rmin=rmax, it prints a single value. one and done, main character energy 👑
  • And with option -I, the points where the interpolation is computed get read from a file instead. flexible! we love options! 🧚

✨ OPTIONS ✨

  • -n — number of equispaced points (default 10). yeah, ten. iconic default, no notes.
  • -r — set the range 'rmin,rmax' (default full x range). if you don't say anything, she just uses everything you gave her 🌈
  • -I — read interpolation points from a file. the choose-your-own-adventure of it all 📖
  • -M — the interpolation method: (default 0)
    • 0 — linear (requires at least 2 points)
    • 1 — cspline (requires at least 3 points)
    • 2 — Akima spline (requires at least 5 points)
  • -O — the type of output: (default 0)
    • 0 — interpolation
    • 1 — first derivative
    • 2 — second derivative
  • -F — specify the input fields separators (default " \t")
  • -h — print this help. your bestie when you forget everything 🥺
  • -v — verbose mode. she will talk. she will tell you things. respect it 💜
heads up babes: those -M methods have minimum point requirements. if you ask for linear with only one point, or cspline with two, or Akima spline with fewer than 5, that's not gonna fly. the numbers are right there, pls respect them 😭
