sigmoid<T>
Description
Sigmoid<T> is a Kernel. If k is an object of class sigmoid<T>, and u and v are objects of class T, then k(u,v) returns
where 
is the scale of the used inner product, 
the bias of the used inner product.
Example
vector< double > u(10); vector< double > v(10); sigmoid< vector< double > > kernel(1.0,0.1); cout << kernel( u, v ) << endl;
Definition
Defined in the KML header <kml/sigmoid.hpp>.
