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