基于Matlab按转子磁链定向矢量控制系统的仿真.(Based on Matlab by the rotor-flux-oriented vector control system simulation.)

四元数法实现对卫星姿态的判断，四元数法实现对卫星姿态的判断，四元数法实现对卫星姿态的判断(Quaternion method on the judgment of the satellite attitude quaternion method to achieve a judgment of the satellite attitude, the quaternion method on the judgment of the satellite attitude )

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)
