Detailed Description

Class representing a generic 3*3 matrix.

It is defined in a row-major order, it means that, in the value buffer, the entire first row is stored first, followed by the entire second row, and so on.
The data value of the matrix can be accessed with the r() method.

| r00  r01  r02 |
| r10  r11  r12 |
| r20  r21  r22 |
