Partial traces

[lkdvos]

Hi Devin,

I was wondering if there is any functionality here to have partial traces on tensors. I am looking for something along the lines of:
$C_{ab} = A_{cabc}$
It seems like this is some kind of reduction, but am I wrong in deducing that the reduction operations currently reduce all the way to a scalar?

Thanks!

In all cases we encountered, this did the trick for such "partial traces":
tblis::add ( +1.0, A, "cabc", 0.0, C, "ab" );
Best,

Thanks a lot for your comment, I think this finally allowed me to actually fully implement the interface!
