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...

bool GiNaC::is_dummy_pair (const idx &i1, const idx &i2)
 Check whether two indices form a dummy pair. More...
 
bool GiNaC::is_dummy_pair (const ex &e1, const ex &e2)

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). More...
 
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). More...
 
void GiNaC::find_dummy_indices (const exvector &v, exvector &out_dummy)
 Given a vector of indices, find the dummy indices. More...
 
size_t GiNaC::count_dummy_indices (const exvector &v)
 Count the number of dummy index pairs in an index vector. More...
 
size_t GiNaC::count_free_indices (const exvector &v)
 Count the number of dummy index pairs in an index vector. More...
 
ex GiNaC::minimal_dim (const ex &dim1, const ex &dim2)
 Return the minimum of two index dimensions. More...
