Friends And Related Function Documentation

vector3 operator*	(	const matrix3x3 &	m,
		const vector3 &	v
	)		[friend, inherited]

Matrix-vector multiplication.

Calculates the product m*v of the matrix m and the column vector represented by v

matrix3x3 operator*	(	const matrix3x3 &	A,
		const matrix3x3 &	B
	)		[friend, inherited]

Matrix-matrix multiplication.

std::ostream& operator<<	(	std::ostream &	co,
		const matrix3x3 &	m
	)		[friend, inherited]

Output a text representation of a matrix.

Print a text representation of the matrix in the standardized form: [ a, b, c ]
[ d, e, f ]
[ g, h, i ]
where the letters represent the appropriate entries in the matrix. Uses the standard output format for the individual entries, separated by ", " for each column, and [ ] indicating each row.
