cubic-spline

A slight modification of Ivan Kuckir's cubic spline implementation, cubic-spline guesses the value of y for any x value on a line. This is helpful for smoothing line graphs.

npm install cubic-spline

usage

const Spline = require('cubic-spline');
 
const xs = [1, 2, 3, 4, 5];

// new a Spline object
const spline = new Spline(xs, ys);
 
// get Y at arbitrary X
console.log(spline.at(1.4));

  console.log(spline.at(* 0.1));
