WebGiven two column vectors a and b, the Euclidean inner product and outer product are the simplest special cases of the matrix product, by transposing the column vectors into row vectors. The inner product is a column vector multiplied on the left by a row vector: More explicitly, The outer product Webin terms of matrices the concatenation of linear functions is the matrix product. Putting these observations together gives the formulation of the chain rule as the Theorem that the linearization of the concatenations of two functions at a point is given by the concatenation of the respective linearizations.

More generally, suppose we differentiate any scalar-valued function f of a vector x with respect to x. By the chain rule, df = ∑ i ∂f ∂xidxi = ∇f ⋅ dx = ∇fTdx. (Technically, I should write df = (∇fTdx)11 to take the unique entry of a 1 × 1 matrix.) Which is the process of the matrix W?
