| 5 | // A simple class to handle 3x3 matrices | 
|---|
| 6 | // The aim of this class is to be able to manipulate 3x3 matrices | 
|---|
| 7 | // and 3D vectors as naturally as possible and make calculations | 
|---|
| 8 | // readable. | 
|---|
| 9 | // For that reason, the operators +, -, * are overloaded. | 
|---|
| 10 | // (Reading a = a + b*2 - c is much easier to read than | 
|---|
| 11 | // a = Sub(Add(a, Mul(b,2)),c)   ) |
