void GiNaC::scalar_products::add	(	const ex &	v1,
		const ex &	v2,
		const ex &	dim,
		const ex &	sp
	)

Register scalar product pair and its value for a specific space dimension.

void GiNaC::scalar_products::add_vectors	(	const lst &	l,
		const ex &	dim = `wild()`
	)

Register list of vectors.

This adds all possible pairs of products a.i * b.i with the value a*b (note that this is not a scalar vector product but an ordinary product of scalars).

void GiNaC::scalar_products::clear ( )

Clear all registered scalar products.
