Sequence of entries to be used for backward computation.
Error sequence, to backpropagate into previous layer.
For the computation, we only used denominator layout. (cf. Wikipedia Page of Matrix Computation) For the computation rules, see "Matrix Cookbook" from MIT.

v0 = a column vector concatenate v2 after v1 (v11, v12, ... v1in1, v21, ...) Q = Rank 3 Tensor with size out, in1 × in2 is its entry. L = Rank 3 Tensor with size out, 1 × (in1 + in2) is its entry. b = out × 1 matrix. output = f( v1'.Q.v2 + L.v0 + b )
