| wolffd@0 | 1 function net = rbfunpak(net, w) |
| wolffd@0 | 2 %RBFUNPAK Separates a vector of RBF weights into its components. |

| wolffd@0 | 4 % Description |
| wolffd@0 | 5 % NET = RBFUNPAK(NET, W) takes an RBF network data structure NET and a |
| wolffd@0 | 6 % weight vector W, and returns a network data structure identical to |
| wolffd@0 | 7 % the input network, except that the centres C, the widths WI, the |
| wolffd@0 | 8 % second-layer weight matrix W2 and the second-layer bias vector B2 |
| wolffd@0 | 9 % have all been set to the corresponding elements of W. |
