我想写一些代码来遍历文件的日期和我想用串行datenum生成的日期。然而,我难以理解datenum生成连续日期值。例如,如果我执行下列伪代码:
myPath = ' D: \ \动物的数据
清单= dir (myPath)
…和if I open the listing I get a struct with one field being the datenum for each file in my directory. I see that the date and time '23-Aug-2021 18:29:25' generates the datenum 7.3839e+05. I don't understand the pattern. How does that date and time generate that exact value?
谢谢! ! !
