核主成分程序：结果中要具体组成主成分的系数,核函数是多项式核函数!

the *getlist(int n=0){/*产生链表*/
the *p;
the *p1;
int i=0;
int j=0;
printf("请输入多项式的系数");
scanf("%d",j);
p=malloc(sizeof(the));
p1=p;
for(i=2;i=n;i++){

scanf("%d",j);
if(n!=i){
*p.next=malloc(sizeof(the));
p=*p.next;
}else{
*p.next=null;
}
}
return p;
}
int thesize(the *p){
int i=1;
while(*p.next!=null){
i++;
p=*p.next;
}
return i;
}
the* addthe(*p1,*p2){/*做加法*/
int size
if(thesize(*p1)thesize(*p2));
size=thesize(*p1);
