void GVectors::Matrix4x4::operator()	(	matindex_t	r,
		matindex_t	c,
		double	v
	)			[inline]

Shorthand operator for setting values.

Parameters:

	r	Row index.
	c	Column index.
	v	Value to set at the given position.

double GVectors::Matrix4x4::operator()	(	matindex_t	r,
		matindex_t	c
	)			const [inline]

Shorthand operator for getting values.
