the day of year是指这一年已经逝去的天数（包括当天） 。在平年中，它的取值范围为 1 到 365，在闰年中，它的取值范围 1到 366。编写一个 MATLAB 程序，输入年，月，日， 输入为对应的 the of year。 (the day of year is the year the number of days have been lost (including the day). In the average year, it ranges from 1 to 365, in a leap year, it ranges from 1 to 366. Write a MATLAB program, enter the year, month, day, enter the corresponding the of year.)
