Classes
class	GiNaC::idx
	This class holds one index of an indexed object. More...
class	GiNaC::varidx
	This class holds an index with a variance (co- or contravariant). More...
class	GiNaC::spinidx
	This class holds a spinor index that can be dotted or undotted and that also has a variance. More...

Namespaces
namespace	GiNaC

Functions
	GiNaC::GINAC_DECLARE_UNARCHIVER (idx)
	GiNaC::GINAC_DECLARE_UNARCHIVER (varidx)
	GiNaC::GINAC_DECLARE_UNARCHIVER (spinidx)
bool	GiNaC::is_dummy_pair (const idx &i1, const idx &i2)
	Check whether two indices form a dummy pair.
bool	GiNaC::is_dummy_pair (const ex &e1, const ex &e2)
	Check whether two expressions form a dummy index pair.
void	GiNaC::find_free_and_dummy (exvector::const_iterator it, exvector::const_iterator itend, exvector &out_free, exvector &out_dummy)
	Given a vector of indices, split them into two vectors, one containing the free indices, the other containing the dummy indices (numeric indices are neither free nor dummy ones).
void	GiNaC::find_free_and_dummy (const exvector &v, exvector &out_free, exvector &out_dummy)
	Given a vector of indices, split them into two vectors, one containing the free indices, the other containing the dummy indices (numeric indices are neither free nor dummy ones).
void	GiNaC::find_dummy_indices (const exvector &v, exvector &out_dummy)
	Given a vector of indices, find the dummy indices.
size_t	GiNaC::count_dummy_indices (const exvector &v)
	Count the number of dummy index pairs in an index vector.
size_t	GiNaC::count_free_indices (const exvector &v)
	Count the number of dummy index pairs in an index vector.
ex	GiNaC::minimal_dim (const ex &dim1, const ex &dim2)
	Return the minimum of two index dimensions.
