# 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')
|
||
|
|
```
|
||
|
|
|
||
|
|
