## net.rim.device.api.math Class Matrix3f

```java.lang.Object net.rim.device.api.math.Matrix3f
```

`public class Matrix3fextends Object`

Defines a 3 x 3 floating point matrix representing a 2D transformation.

Vectors are treated as columns, resulting in a matrix that is represented as follows, where x and y are the translation components of the matrix:

```   1  0  x
0  1  y
0  0  1
```

Since matrix multiplication is not commutative, multiplication must be done in the correct order when combining transformations. Suppose we have a translation matrix T and a rotation matrix R. To first rotate an object around the origin and then translate it, you would multiply the two matrices as TR. Likewise, to first translate the object and then rotate it you would do RT. So generally, matrices must be multiplied in the reverse order in which you want the transformations to take place (this also applies to the ```scale, rotate, and translate``` methods below; these methods are convenience methods for post-multiplying by a matrix representing a scale, rotation, or translation).

Passing a matrix to OpenVG is a simple and efficient operation since the underlying array for the matrix is stored in a format that is directly compatible with OpenVG.

```   `// Create a matrix to translate by (10, -2)`
Matrix3f translation = `new` Matrix3f();
translation.set(1, 0, 10,
0, 1, -2,
0, 0, 1 );

`// Pass our matrix to OpenVG`

Note: In the case of repeated local transformations (i.e. rotate by 0.76 radians, then translate by 2.1 along the X-axis, then ...), it is better to use `Transform2D` (which is optimized for that kind of usage).
