The matrices package provides some typical matrix calculations, with more added as deemed necessary. Operations include addition, negation, product, transposition, augmentation, slicing, equality with precision, and finding the norm, determinant, and inverse.
To install matrices, do this:
$ npm install matrices
$ npm install $ npm run-script build
Otherwise you can use the CoffeeScript compiler to build things in a way you like, e.g. by running:
$ coffee -c -o lib src
Another way to get annotated source code is to clone this repository and use Docco with Beans:
$ npm run-script docs
$ docco src/*.coffee src/**/*.coffee
docs directory should be created in the working directory root.
