A toolkit for using vectors and matrices

Install

Install the package from npm:

npm install --save @footmap/matrix

Or, using yarn:

yarn add @footmap/matrix

Usage

// foomap-matrix-demo.js
import { Vector, Matrix } from '@footmap/matrix'

const vector2 = new Vector(7, 3);
const vector3 = new Vector(7, 3, 9);
const matrix2x2 = new Matrix([1, 2], [3, 4]);
const matrix2x3 = new Matrix([1, 2, 3], [4, 5, 6]);
const matrix3x2 = new Matrix([1, 2], [3, 4], [5, 6]);
// 2D => 2D
console.log(vector2.transform(matrix2x2));
// Vector { components: [ 13, 33 ] }

// 3D => 2D
console.log(vector3.transform(matrix2x3));
// Vector { components: [ 40, 97 ] }

// 2D => 3D
console.log(vector2.transform(matrix3x2));
// Vector { components: [ 11, 33, 57 ] }
console.log(vector2.transform(matrix2x3));
// Error: Matrix columns length should be equal to vector components length.
