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