WebWe work with the standard inner product in a vector space hu,vi = uTv, u,v ∈ Rn, and with the trace inner product in a matrix space hM,Ni = traceMTN, M,N ∈ Mn(R),or hM,Ni = traceM∗N, M,N ∈ Mn(C), where traceM = Xn i=1 mii. This definition holds in Mn as well as in Sn. The corresponding norm is the Frobenius norm, defined by kMkF = √ WebConsider the scalar function and its first derivative h ( s) = f ( s) g ( s) h ′ = f g ′ + g f ′ Your general function applies this scalar function to a matrix argument, i.e. H = h ( X), then takes the trace. So the function, differential and gradient are given by ϕ = t r ( H) d ϕ = t r ( H ′ …
