wolffd@0 23 Description
wolffd@0 24 </h2>
wolffd@0 25 <CODE>g = rbfderiv(net, x)</CODE> takes a network data structure <CODE>net</CODE>
wolffd@0 26 and a matrix of input vectors <CODE>x</CODE> and returns a three-index matrix
wolffd@0 27 <CODE>g</CODE> whose <CODE>i</CODE>, <CODE>j</CODE>, <CODE>k</CODE> element contains the
wolffd@0 28 derivative of network output <CODE>k</CODE> with respect to weight or bias
wolffd@0 29 parameter <CODE>j</CODE> for input pattern <CODE>i</CODE>. The ordering of the
wolffd@0 30 weight and bias parameters is defined by <CODE>rbfunpak</CODE>. This
wolffd@0 31 function also takes into account any mask in the network data structure.
