说明：  为MATLAB中的图形增加标签，从而可以有效地表示图形意义，防止读不懂图的情况( BWLABEL supports 2-D inputs only, whereas BWLABELN support any input dimension. In some cases you might prefer to use BWLABELN even for 2-D problems because it can be faster. If you have a 2-D input whose objects are relatively "thick" in the vertical direction, BWLABEL will probably be faster otherwise BWLABELN will probably be faster.)

When we decimate the signal, only the sampling rate decreases but the frequency content remains same

题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？ 1.程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去 　　　　　　掉不满足条件的排列。 (Title: There are numbers 1,2,3,4, how many can be composed of distinct three-digit numbers without repetition? Is how much? 1. Program Analysis: fill in the hundred, ten, a bit of the numbers are 1,2,3,4. Composed of all the permutations and then remove the arrangement does not meet the conditions.)
