template<typename IndexContainer>
inline TensorBlockCanonicalizer(const IndexContainer &external_indices)

virtual ExprPtr apply(AbstractTensor &t) const override

Implements TensorCanonicalizer::apply

Note

Canonicalizes t by sorting its bra (if t.symmetry()==Symmetry::nonsymm ) or its bra and ket (if t.symmetry()!=Symmetry::nonsymm ), with the external indices appearing “before” (smaller particle indices) than the internal indices
