Essentially a wrapper to endpoints with the appropriate period specified; the resulting value derived from counting the endpoints
基本上是一个包装指定相应周期内所产生的价值来自计数的端点endpoints
As a compromise between simplicity and accuracy, the results will always round up to the nearest complete period. So n**** - 1 will return the completed periods.
作为一种妥协之间的简单性和准确性,结果总是向上舍入到最近的完整的周期。所以N **** - 1将返回已完成的期限。
For finer grain detail one should call a higher frequency n**** function.
细化晶粒的详细信息,应该调用一个更高频率的N ****功能。
An alternative summary can be found with periodicity and unclass(periodicity(x)).
另一种方法的总结,可以发现periodicity和unclass(periodicity(x))。
