# gl-mat2 [](http://github.com/badges/stability-badges)
Part of a fork of [@toji](http://github.com/toji)'s
[gl-matrix](http://github.com/toji/gl-matrix) split into smaller pieces: this
package contains `glMatrix.mat2`.
## Usage
[](https://nodei.co/npm/gl-mat2/)
### `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:
``` javascript
var scale = require('gl-mat2').scale
var scale = require('gl-mat2/scale')
```
