描述----------Description----------
Not really used in practice. The function IsEarly can be used to tell if an object comes from an earlier version of wavethresh. Note that the earlier version only has a wd.object class object so there is only a method for that.
没有真正在实践中使用。的功能IsEarly可以用来告诉如果对象来自早期版本的wavethresh,的。请注意,早期版本只有一个wd.object类对象,所以只有一个方法的。
