Hi! I am trying to implement cleanly the tensor contraction. What I'd 
like to do is something like this.

Let A = matrix of A^{ijk} be a 3-tensor, now how do I write something like

C^{ik} = A^{ijk} v_j

using the summing notation? I am trying to avoid making simple For cycles...


Thanks & Cheers!
