5 % W = NETPAK(NET) takes a network data structure NET and combines the
|
Daniel@0
|
6 % component weight matrices into a single row vector W. The facility

7 % to switch between these two representations for the network

Daniel@0
|
8 % parameters is useful, for example, in training a network by error
|
Daniel@0
|
9 % function minimization, since a single vector of parameters can be

Daniel@0
|
10 % handled by general-purpose optimization routines. This function also

Daniel@0
|
11 % takes into account a MASK defined as a field in NET by removing any

Daniel@0
|
12 % weights that correspond to entries of 0 in the mask.
