Daniel@0 4 % Description
Daniel@0 5 %
Daniel@0 6 % E = NETERR(W, NET, X, T) takes a weight vector W and a network data
Daniel@0 7 % structure NET, together with the matrix X of input vectors and the
Daniel@0 8 % matrix T of target vectors, and returns the value of the error
Daniel@0 9 % function evaluated at W.
Daniel@0 10 %
Daniel@0 11 % [E, VARARGOUT] = NETERR(W, NET, X, T) also returns any additional
Daniel@0 12 % return values from the error function.
