从n个不同元素中任取m（m≤n）个元素，按照一定的顺序排列起来，叫做从n个不同元素中取出m个元素的一个排列。当m=n时所有的排列情况叫全排列。 公式：全排列数f(n)=n!(定义0!=1)
A full array producing method that uses chaotic sequence was presented,which is based on the random character,sensitivity of original value and ergodicity in interzone. Then the full array matrix was applied in image scrambling.
