fsvmclass.m

些程序是对多类分类的另一种处理方法

function [xsup,w,d,pos,alpha]=fsvmclass(x,y,c,lambda,kerneloption,verbose,span,alphainit)
A=y;
b=0;
ps=kerneloption.matrix;
H=ps.*(y*y');
e=ones(size(y));
[alpha,lambda,pos,ahphaaux]=monqp(H,e,A,b,c,lambda,verbose,x,ps,alphainit);
alphaall=zeros(size(e));
alphaall(pos)=alpha;
xsup=[];
ysup=y(pos);
w=(alpha.*ysup);
d=lambda;
