Frobenius matrix norm

Web14.16 Frobenius norm of a matrix. The Frobenius norm of a matrix A ∈ Rn×n is defined as kAkF = √ TrATA. (Recall Tr is the trace of a matrix, i.e., the sum of the diagonal entries.) (a) Show that kAkF = X i,j Aij 2 1/2. Thus the Frobenius norm is simply the Euclidean norm of the matrix when it is considered as an element of Rn2. Note also ...
