rbfaddkernel.m

The goal of SPID is to provide the user with tools capable to simulate, preprocess, process and clas

function y = RBFaddkernel(x1, x2, sigma),
% function y = RBFaddkernel(x1, x2, sigma),

%y = exp( - (norm(x1 - x2))^2/(sigma^2 ) );
[n1,D]=size(x1);
n2=size(x2,1);
y=zeros(n1,n2);
for d=1:D,
    y = y+exp(-(x1(:,d)-x2(:,d))*(x1(:,d)-x2(:,d))'/(sigma^2));
end
