I have a tensor A \in R^{m,n,d} and a matrix B \in R^{m,d}.
Let A_i denote the n \times d matrix at location A[i].
Let b_j denote the vector contained by the j'th row of B, i.e. b_j = B[j].
I am trying to figure out the right set of MXNet operations to efficiently compute the matrix C whose k\text{'th} row is equal to the matrix-vector product of A_k * b_k = \texttt{nd.dot}(A[k], B[k]).
Any help is greatly appreciated.
