Dear Dhaneshwar, I believe this may be what you are looking for: avec = Array[a, 3] bvec = Array[b, 3] ctens = Array[c, {3, 3, 3, 3}] ab[j_, k_] := Sum[avec[[i]] ctens[[i, j, k, m]] bvec[[m]], {i, 1, 3}, {m, 1, 3}] This may be enough to get you started, but there is also documentation for tensors (type tensor into the help browser) in the documentation.
