Constructor & Destructor Documentation

CSubSpace::CSubSpace	(	size_t	dim_space = 3,
		size_t	dim_sub = 0
	)

Constructs a CSubSpace of the specified dimension.

Parameters:

	dim_space	dimension of the Euclidian vector space we are working in
	dim_sub	dimension of the subspace to be created

CSubSpace::CSubSpace	(	const CVector &	pi,
		const CMatrix &	mi,
		subspaceflags_t	createflags = GEOCPP_FROM_EQS
	)

Constructs a CSubSpace from a point and either the equations or a base of the subspace.

Parameters:

	pi	a point in the subspace
	mi	a matrix containing the equations or the base of the subspace
	createflags	specifies whether we were given the equations or the base of the subspace
