Daniel@0 24 Description
Daniel@0 25 </h2>
Daniel@0 26 <CODE>w = netpak(net)</CODE> takes a network data structure <CODE>net</CODE> and
Daniel@0 27 combines the component weight matrices into a single row
Daniel@0 28 vector <CODE>w</CODE>. The facility to switch between these two
Daniel@0 29 representations for the network parameters is useful, for example, in
Daniel@0 30 training a network by error function minimization, since a single
Daniel@0 31 vector of parameters can be handled by general-purpose optimization
Daniel@0 32 routines. This function also takes into account a <CODE>mask</CODE> defined
Daniel@0 33 as a field in <CODE>net</CODE> by removing any weights that correspond to
Daniel@0 34 entries of 0 in the mask.
