gl-mat2

Part of a fork of @toji's gl-matrix split into smaller pieces: this package contains glMatrix.mat2.

Usage

mat2 = require('gl-mat2')

Will load all of the module's functionality and expose it on a single object. Note that any of the methods may also be required directly from their files.

For example, the following are equivalent:

var scale = require('gl-mat2').scale
var scale = require('gl-mat2/scale')
