Function Documentation

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 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 cummutative; i.e. AB != BA, so the ordering of arguments m1 and m2 matters.

Parameters:

[in]	m1	The first matrix. Must be non-NULL.
[in]	m2	The second matrix. Must be non-NULL.
[out]	dst	The matrix for the results to be placed.
