Numerical interpolation and extrapolation lib

For docs and more information go to GitHub project page.

Synopsis

Everpolate provides a set of common interpolation algorithms implementations. Implementations given for interpolation are also implementations for extrapolation. Since it's written in JavaScript, everpolate could be used for web browser, Node and so forth.

For usage with Meteor look at everpolate-meteor.

Features:

• Value Interpolation
• Step Function Interpolation
• Linear Interpolation
• Polynomial Interpolation
• Linear Regression

everpolate's Issues

Missing Bower and GitHub release for v0.0.3

Hi @BorisChumichev,

unfortunately, there is only one npm release for version 0.0.3 but no bower and github release. Could you possibly do this? That would be great.

Thanks in advance!

Partial import support to decrease bundle size served to the client side

Example:

import linearInterpolation from 'everpolate.linear'

N-dimensional functions support

Partial application support

This one will require backward incompatible API change.

Example:

import polynomialInterpolation from 'everpolate.polynomial'
const [ knownValuesX, knownValuesY ] = [[...], [...]]
const resolveValues = polynomialInterpolation(knownValuesX, knownValuesY)
// now resolveValues is an evaluation function:
resolveValues(x) // -> y
resolveValues(x) // -> y

Step interpolation example

Hello there.

Could you provide logical example how step interpolation works?

Suppose I have a timeserie which has as x values = [ 5,6,7,10] and as y values = [ 50, 49, 48, 45 ] .
How can i use the step function to "fill in the gaps" and return the resulting array so I know what value y is at value x = 8 and x = 9?

Dojo support?

Hello, can this library be used with Dojo?

Add everpolate to website for demo

Hi !

Please, like on momentjs/lodash/... websites please add everpolate.browserified to your gh-pages branche build.

Like this, people can try your tool directly in their browser on your website without having to install it before

Nearest neighbour interpolations

Solving for x using linear interpolation

Is there a way to extend your linear interpolation logic so I can solve for x using a specified y value?

interpolation 2d

How to do interpolation 2d like Scipy intrep2d?
