Dead simple data interpolation.
Usage
interpolate.js is a simple data interpolation library that allows for interpolation of linear and bilinear functions/datapoints.
To use the library, install it via npm:
npm install js-interpolate
Then, you can use the library as follows:
Linear interpolation enables data interpolation of a single dimension array of data points. If the requested x
is out of bounds, the function will expand the data points basing off the first two data points.
import { linearInterpolation } from 'js-interpolate';
const data = [1, 2, 3, 4, 5];
console.log(linearInterpolation(data, 2.5)) // 3.5
console.log(linearInterpolation(data, 5)) // 6
Bilinear interpolation enables data interpolation of a two-dimensional array of data points where the x
and y
dimensions are the axis of the provided grid and z
are the provided data points. If the requested x
or y
is out of bounds, it will provide an estimate given the nearest data points.
import { createBilinearInterpolationFunction } from 'js-interpolate';
const data = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
];
const bilinearInterpolation = createBilinearInterpolationFunction(data);
bilinearInterpolation(0.5, 0.5) // 3
