If you consider a linear map between vector spaces (such as the Jacobian) J: u ∈ U → v ∈ V, the elements v = J u have to agree in shape with the matrix-vector definition: the components of v are the inner products of the rows of J with u. In e.g. linear regression, the (scalar in this case) output space is a weighted combination ...
