vect

A (Multidimensional) Lightweight Vector Computation Library

NOTE that this library makes an assumption that vectors are simply lists (Array) of numbers, such as [1, 2, 3, 4].

Install

npm install {} or just add vect.min.js to your page.

API

Summary:

• Addition
• Magnitude
• Dot Product
• Cosine Similarity

Addition - vect.add()

Adds n vectors, returning a vector Array.

vect.add([1, 2, 3], [3, 2, 1]); // x

Magnitude - vect.mag(a), or vect.magnitude(a)

Computes the magnitude of a vector a, returning a number.

vect.mag([1, 2, 3]); // x

Dot Product - vect.dot(a, b)

Computes the dot product of two vectors a and b, returning a number.

vect.dot([1, 2, 3], [3, 2, 1]); //

Cosine Similarity (Angle) - vect.angle(a, b)

Computes the cosine similarity (or angle between) two vectors a and b, returning a number.

vect.angle([1, 2, 3], [1, 2, 3]); // 1
