function [h, varargout] = nethess_weighted(w, net, x, t, eso_w, varargin)
%NETHESS Evaluate network Hessian
%
% Description
%
% H = NETHESS(W, NET, X, T) takes a weight vector W and a network data
% structure NET, together with the matrix X of input vectors and the
% matrix T of target vectors, and returns the value of the Hessian
% evaluated at W.
%
% [E, VARARGOUT] = NETHESS(W, NET, X, T, VARARGIN) also returns any
% additional return values from the network Hessian function, and
% passes additional arguments to that function.
