+function w = netpak(net)
+%NETPAK	Combines weights and biases into one weights vector.
+%
+%	Description
+%	W = NETPAK(NET) takes a network data structure NET and combines the
+%	component weight matrices  into a single row vector W. The facility
+%	to switch between these two representations for the network
+%	parameters is useful, for example, in training a network by error
+%	function minimization, since a single vector of parameters can be
+%	handled by general-purpose optimization routines.  This function also
+%	takes into account a MASK defined as a field in NET by removing any
+%	weights that correspond to entries of 0 in the mask.
+%
