Properties of the Trace and Matrix Derivatives
web.stanford.edu2 Matrix multiplication First, consider a matrix A ∈ Rn×n. We have that AAT = Xn i=1 a ia T, that is, that the product of AAT is the sum of the outer products of the columns of A. To see this, consider that (AAT) ij = Xn p=1 apiapj because the i,j element is the ith row of A, which is the vector ha1i,a2i,···,anii, dotted with the jth ...
