+%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.
+%
