a=zeros(10,10)；matlab中norm函數的用法、i=1;j=1;matlab中histfit函數，while i<=10while j<=10a(i,j)=normrnd(2,4);j=j+1;endi=i+1;end輸出為：a=[ -2.6033? ? 0.7369? ? 2.7789? ? 5.6589? ?-0.2654? ? 3

函數名功能函數形成參數描述skb_queue_empty檢查隊列是否為空int skb_queue_empty (struct sk_buff_head * list)list為隊列頭如果隊列為空返回真，否則返回假skb_get引用緩沖區struct sk_buff * skb_get (struct sk_buff * skb)skb為要引用的緩沖區對套接字緩沖區再引用
