A spectral function of a symmetric matrix X is a function which depends only on the eigenvalues of X, A1 (X) ~ A2 (X) ~.-. > An (X), and may be written as .f(A1 (X), A2(X) ..... An (X)) for some symmetric function /. In this paper, we assume that / is a C 1,1 function and discuss second-order direct
