I'm trying to compare two tensors of the same rank but different indices. For example, some thing like
auto T1 = ITensor(s1,prime(s1));
auto T2 = ITensor(s2,prime(s2));
Where I'd want to have
s2' go to
s1' prime and then (I assume) easily compare them using the norm. My specific use case is that these are
Site type indices if that helps.
Is there a way to do this efficiently?
