wolffd@0 24 Description
wolffd@0 25 </h2>
wolffd@0 26 <CODE>net = rbfsetfw(net, scale)</CODE> sets the widths of
wolffd@0 27 the basis functions of the
wolffd@0 28 RBF network <CODE>net</CODE>.
wolffd@0 29 If Gaussian basis functions are used, then the variances are set to
wolffd@0 30 the largest squared distance between centres if <CODE>scale</CODE> is non-positive
wolffd@0 31 and <CODE>scale</CODE> times the mean distance of each centre to its nearest
wolffd@0 32 neighbour if <CODE>scale</CODE> is positive. Non-Gaussian basis functions do
wolffd@0 33 not have a width.
