Definition and operations for 3x3 fixed point matrices.
| void eina_matrix3_f16p16_identity | ( | Eina_Matrix3_F16p16 * | m | ) | 
Sets the given fixed point matrix to the identity matrix.
| [in] | m | The fixed point matrix to set. | 
This function sets m to the identity matrix. No check is done on m.
| void eina_matrix3_f16p16_compose | ( | const Eina_Matrix3_F16p16 * | m1, | 
| const Eina_Matrix3_F16p16 * | m2, | ||
| Eina_Matrix3_F16p16 * | dst | ||
| ) | 
Sets dst as the matrix multiplication (composition) of two Eina_F16p16 matrices.
| [in] | m1 | The first matrix. Must be non-NULL. | 
| [in] | m2 | The second matrix. Must be non-NULL. | 
| [out] | dst | The results matrix. | 
In matrix multiplication, AB, the resultant matrix is created from the rows of A multiplied against the columns of B and summed. This is not a commutative; i.e. AB != BA, so the ordering of arguments m1 and m2 matters.

| Eina_Matrix_Type eina_matrix3_f16p16_type_get | ( | const Eina_Matrix3_F16p16 * | m | ) | 
Returns the type of the given fixed point matrix.
| [in] | m | The fixed point matrix. | 
This function returns the type of the matrix m. No check is done on m.
