+function g = netderiv(w, net, x)
+%NETDERIV Evaluate derivatives of network outputs by weights generically.

+%	Description
+%
+%	G = NETDERIV(W, NET, X) takes a weight vector W and a network data
+%	structure NET, together with the matrix X of input vectors, and
+%	returns the gradient of the outputs with respect to the weights
+%	evaluated at W.
