vectorious codeclimate travis-ci gulp npm

High performance linear algebra.

vectorious

version travis climate coverage

A high performance linear algebra library, written in JavaScript and optimized with C++ bindings to BLAS.

Usage

In node.js
$ npm install vectorious
var v = require('vectorious'),
    Matrix = v.Matrix,
    Vector = v.Vector,
    BLAS = v.BLAS; // access BLAS routines

Will use your local BLAS copy (if any). Some notes for different operating systems:

In browser

Download a release and use it like this:

<script src="vectorious-4.x.x.min.js"></script>
<script>
  var A = new Matrix([[1], [2], [3]]),
      B = new Matrix([[1, 3, 5]]),
      C = A.multiply(B);

  console.log('C:', C.toArray());
  /* C: [
    [1, 3, 5],
    [2, 6, 10],
    [3, 9, 15]
  ] */
</script>

Compared to other libraries

The following benchmarks compare Vectorious 4.1.0 with three popular matrix/vector libraries:

The graphs show operations per second on the vertical (y) axis.

Below is a graph comparing the vector operations add, angle, dot, magnitude (aka L2-norm), normalize and scale.

The operations were performed on vectors generated with Vector.random(1048576).
