Member Function Documentation

add() [1/2]

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

Register scalar product pair and its value.

Definition at line 1349 of file indexed.cpp.

References spm.

add() [2/2]

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.

Definition at line 1354 of file indexed.cpp.

References spm.

add_vectors()

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).

Definition at line 1359 of file indexed.cpp.

clear()

void GiNaC::scalar_products::clear

(

)

Clear all registered scalar products.

Definition at line 1367 of file indexed.cpp.

References spm.

is_defined()

bool GiNaC::scalar_products::is_defined	(	const ex &	v1,
		const ex &	v2,
		const ex &	dim
	)		const

Check whether scalar product pair is defined.

Definition at line 1373 of file indexed.cpp.

References spm.

evaluate()

ex GiNaC::scalar_products::evaluate	(	const ex &	v1,
		const ex &	v2,
		const ex &	dim
	)		const

Return value of defined scalar product pair.
