Vector<T, Size+1>& Eigen::affToProj	(	const Vector< T, Size > &	vector,
		Vector< T, Size+1 > *	ret
	)			`[inline]`

Converts an "affine" vector into the equivalent "projective" vector. Thus, if the input affine vector is $(x_1,\ldots,x_n)$ , then the output projective vector is $(x_1,\ldots,x_n,1)$ .

Vector<T, Size>& Eigen::projToAff	(	const Vector< T, Size+1 > &	vector,
		Vector< T, Size > *	ret
	)			`[inline]`

Converts a "projective" vector into the equivalent "affine" vector. Thus, if the input projective vector is $(x_1,\ldots,x_{n+1})$ , then the output affine vector is

$(\frac{x_1}{x_{n+1}},\ldots,\frac{x_n}{x_{n+1}}).$
