计算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，输出为对应的该天是当年的第几天。 闰年是这样规定的 1）.能被400整除的年为闰年 2）能被100整除但不能被400整除的年不为闰年 3）.能被4整除但不能被100整除年为闰年 4）.其余的年份不为闰年 (This year has calculated the number of days elapsed (including that day). In non-leap year, it ranges from 1 to 365 in a leap year, it s the range of 1 to 366. Write a MATLAB program, enter the year, month, day, corresponding to the output of the first year of the day is a few days. This leap is required 1) is divisible by 400 is a leap year 2) can be divisible by 100 but not divisible by 400 years is not a leap year 3) be divisible by 4 but not divisible by 100 is a leap year 4) the rest of the year is not leap year)

MATLAB中求解非线性系统平衡点的方程，对分析其动力学稳定性大有裨益(MATLAB to solve the nonlinear system equilibrium point of the equation, the analysis of its dynamic stability of great benefit)
