What is the difference of "Spread" parameter in GRNN and RBF neural network? Does it have any relationship with core RBF function in GRNN algorithm or not?

No difference. It is the distance from the center of a Gaussian where te value is one-alf of the peak value
Hope this helps.

Dear greg heath. could you please explain how to use the newgrnn function for 5 features(inputs) and a single output... when i tried giving the inputs and outputs it showed me an error which was... Error using network/subsasgn>network_subsasgn (line 528) net.IW{1,1} must be a 1-by-2000 matrix.
Error in network/subsasgn (line 13) net = network_subsasgn(net,subscripts,v,netname);
Error in newgrnn>create_network (line 123) net.iw{1,1} = p';
Error in newgrnn (line 67) net = create_network(param);

1. Post your code
2. Run it on the data in the help and doc documentation
3. Create a 5-D input by adding small noise to 4 copies of the original
4. Run it on the 5-D input that you created.
Hope this helps.
Thank you for formally accepting my answer
Greg
