说明： 在处理数据的时候我们经常要算各个区间的频数,但是在matlab中没有这样的命令.当数据比较大的时候自己数就比较麻烦,这里编了个小程序,(Handle data in a time when we often have to count the frequency of each interval, but there is no such matlab in command. When the data when the relatively large number of on its own is too much trouble here编了个small procedures,)
