Simple Interpolation

Simple Interpolation

A simple interpolation module that construct new data points within the range of a discrete set of known data points, example.

Module Installation

You can install this module using NPM:

npm install simple-interpolation --save

Module Single Interpolation

  Simple Schema of Single interpolation

  ---|---|
  x1 |y1 |
  ---|---|
   x | y |
  ---|---|
  x2 |y2 |
  ---|---|

Simple using way

import { single } from 'simple-interpolation';

const points = [{ x: 1, y: 1}, { x: 2, y: 2 }];

single(points)({ x: 1.5 }); // y -> 1.5
single(points)({ y: 1.5 }); // x -> 1.5

Or you can use JavaScript

var simple = require('simple-interpolation');

var points = [{ x: 1, y: 1}, { x: 2, y: 2 }];
var single = simple.single(points);

single({ x: 1.5 }); // y -> 1.5
single({ y: 1.5 }); // x -> 1.5

Or you can use JavaScript(Babale)

import { single } from 'simple-interpolation';

const points = [{ x: 1, y: 1}, { x: 2, y: 2 }];

const f = single(points);

f({ x: 1.5 }); // y -> 1.5
f({ y: 1.5 }); // x -> 1.5

Or you can use TypeScript

import { single } from "simple-interpolation";

const points = [{ x: 1, y: 1}, { x: 2, y: 2 }];

const f = single(points);

f({ x: 1.5 }); // y -> 1.5
f({ y: 1.5 }); // x -> 1.5

Module Double Interpolation

  Simple Schema of Double interpolation

     |x1 | x |x2 |
  ---|---|---|---|
  y1 |z11|   |z12|
  ---|---|---|---|
   y |   | z |   |
  ---|---|---|---|
  y2 |z21|   |z22|
  ---|---|---|---|

Simple way

import { double } from 'simple-interpolation';

const points = [{ x: 1, y: 1, z: 11 }, { x: 2, y: 1, z: 12 }, { x: 1, y: 2, z: 21 }, { x: 2, y: 2, z: 22 }];

double(points)({ x: 1.5, y: 1.5 }); // z -> 16.5
double(points)({ x: 1.5, z: 16.5 }); // y -> 1.5
double(points)({ y: 1.5, z: 16.5 }); // x -> 1.5

Or you can use JavaScript

var simple = require('simple-interpolation');
var points = [{ x: 1, y: 1, z: 11 }, { x: 2, y: 1, z: 12 }, { x: 1, y: 2, z: 21 }, { x: 2, y: 2, z: 22 }];

var f = simple.double(points);

f({ x: 1.5, y: 1.5 }); // z -> 16.5
f({ x: 1.5, z: 16.5 }); // y -> 1.5
f({ y: 1.5, z: 16.5 }); // x -> 1.5

Or you can use JavaScript(Babale)

import { double } from 'simple-interpolation';

const points = [{ x: 1, y: 1, z: 11 }, { x: 2, y: 1, z: 12 }, { x: 1, y: 2, z: 21 }, { x: 2, y: 2, z: 22 }];

const f = double(points);

f({ x: 1.5, y: 1.5 }); // z -> 16.5
f({ x: 1.5, z: 1.5 }); // y -> 1.5
f({ y: 1.5, z: 1.5 }); // x -> 1.5

Or you can use TypeScript

import { double } from "simple-interpolation";

const points = [{ x: 1, y: 1, z: 11 }, { x: 2, y: 1, z: 12 }, { x: 1, y: 2, z: 21 }, { x: 2, y: 2, z: 22 }];

const f = double(points);

f({ x: 1.5, y: 1.5 }); // z -> 16.5
f({ x: 1.5, z: 16.5 }); // y -> 1.5
f({ y: 1.5, z: 16.5 }); // x -> 1.5
