radbas

Radial basis transfer function

Graph and Symbol

Syntax

A = radbas(N,FP)

Description

radbas is a neural transfer function. Transfer functions calculate a layer’s output from its net input.

A = radbas(N,FP) takes one or two inputs,

N

S-by-Q matrix of net input (column) vectors

FP

Struct of function parameters (ignored)

and returns A, an S-by-Q matrix of the radial basis function applied to each element of N.

Examples

Here you create a plot of the radbas transfer function.

n = -5:0.1:5;
a = radbas(n);
plot(n,a)

Assign this transfer function to layer i of a network.

net.layers{i}.transferFcn = 'radbas';

Algorithms

a = radbas(n) = exp(-n^2)
