# 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')
``````

## API

### `mat2.adjoint(out:mat2, a:mat2)`

Calculates the adjugate of a mat2

### `mat2.copy(out:mat2, a:mat2)`

### `mat2.determinant(a:mat2)`

Calculates the determinant of a mat2

### `mat2.frob(a:mat2)`

Returns Frobenius norm of a mat2

### `mat2.identity(out:mat2)`

Inverts a mat2

### `mat2.ldu(L:mat2, D:mat2, U:mat2, a:mat2)`

Returns L, D and U matrices (Lower triangular, Diagonal and Upper triangular) by factorizing the input matrix

### `mat2.multiply(out:mat2, a:mat2, b:mat2)`

Multiplies two mat2's

### `mat2.rotate(out:mat2, a:mat2, rad:Number)`
