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.
- Parameters:
-
[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.
