spline interpolation
npm install cubic-spline-browserifiedThis library is a fork of cubic-spline.
The only intent of the fork is to get the library work in a browser out-of-the-box.
A pull request has been sent to upstream;
if and when it is merged, you will perhaps prefer the upstream version.
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.
``sh`
npm install cubic-spline-browserified
`js
const Spline = require('cubic-spline-browserified'); // Still works
const xs = [1, 2, 3, 4, 5];
const ys = [9, 3, 6, 2, 4];
// new a Spline object
const spline = new Spline(xs, ys);
// get Y at arbitrary X
console.log(spline.at(1.4));
// interpolate a line at a higher resolution
for (let i = 0; i < 50; i++) {
console.log(spline.at(i * 0.1));
